Workflow condition on Checkbox field disappears after Save

Summary:

Hi Everyone,
We are encountering an issue when creating/editing workflow rules for Customer Work Orders (Parent Entity: Service Request).
Whenever we add a condition based on a Checkbox field (e.g., and when Need Repair is true), we can click Save and Deploy successfully. However, when we reopen the workflow rule to edit it, the condition is completely missing—it only shows a blank and when line.
This behavior only seems to occur for boolean/checkbox type fields. Standard text/choice fields retain their values without issue.

Has anyone encountered this bug in recent releases?Is there a known workaround.
