Issue: Turnitin Options Appearing Without Integration

Canvas Area: Assignments / Plagiarism Framework

Status: Confirmed Canvas Bug – Fix Pending

Canvas Case #: CASE-13231192

Expected Behavior Instructors should only see plagiarism review options for tools currently integrated into the Canvas instance. References to Turnitin should not appear if the tool is not configured.

Observed Behavior Instructors are seeing options to submit assignments via Turnitin despite the institution using Copyleaks and never having installed a Turnitin integration.

Impact / Severity Medium. Causes instructor confusion and administrative overhead for institutions using alternative plagiarism frameworks.

Notes from Canvas Support

Nov 10, 2025 – Case opened with Canvas Support.
Nov 10, 2025 – Canvas confirmed this is a known product defect; engineers are currently investigating a resolution.

Workaround (if available) Instructors should ignore the Turnitin references and continue to select Copyleaks from the plagiarism review dropdown.

Issue: Quiz Submissions Not Visible in Gradebook and False “Multiple Session” Warnings

Canvas Area: Quizzes / Gradebook / Session Management

Status: Confirmed Canvas Bug – Escalated to L2 Support

Canvas Case #: CASE-13485141

Expected Behavior Instructors should be able to view all student quiz submissions directly from the Gradebook when a student has completed an attempt. Students should only receive a “multiple session” warning if a quiz is actively open in more than one browser window, tab, or device.

Observed Behavior Instructors cannot see some completed quiz submissions from the Gradebook, even though quiz attempt logs show full student activity and students can view their own results from the module. Students receive a “You have already started this quiz in a different session” warning when using a single device and browser window, and in some cases before opening the quiz for the first time.

Impact / Severity Medium. Causes instructor uncertainty about whether a submission occurred, student anxiety over potential academic integrity flags, and increased administrative workload to manually review moderation logs and Canvas support transcripts.

Issue: Letter Grades Persistent in Total Column

Canvas Area: Gradebook
Status: Resolved
Canvas Case #: CASE-12999132

Expected Behavior When the "Enable course grading scheme" option is unchecked in Course Settings, the Total column in the Gradebook should display only numerical values (percentage or points) and hide letter grades.

Observed Behavior Letter grades continue to display in the Gradebook Total column even after the instructor disables the grading scheme. Engineering investigation suggests the API parameter for the grading scheme may remain stuck in a "true" state at the course level.

Impact / Severity Medium. Impacts grade privacy and clarity; students may see a calculated letter grade that the instructor does not intend to use or has not yet finalized.
