To reproduce:
- Create a kanban (with any tracker)
- Modify the kanban tracker. Add a radio button field bound to user groups (for example "Project Members", "Contributors", "Integrators", etc. Choose at least one "Dynamic user group" as possible value like "Project Members", "Project Administrators".
- Go to the kanban and click on "Add a new <tracker name>" button
- The artifact modal will open and there will be an error like:
kanban-e0306fe61949763b5a63.js:285 Error: [$parse:syntax] Syntax Error: Token '_3' is an unexpected token at column 4 of the expression [321_3] starting at [_3].
If you select a user group in the radio button field and submit the modal, the value is not saved.
