Steps to Reproduce

1. Create a new Kanban project with sample issues.
2. Create a new plan and linked to the kanban board.
3. Change the plan view settings to group by "Teams"
4. In "Teams" tab, edit the teams and put 300 capacity hours.
5. Create a new Epic and link to a Team. Then, link to a story.
6. You should see 37.5 per weekly planning.
7. If you modify one of the weekly planning from 37.5 to 37 and submit the changes. It works.
8. However, if I change it back to 37.5 is not possible anymore.
   

Expected Results

Based on the fact that team capacity can be measured using floating numbers, it should allow user manually change the duration iteration to a decimal numbers.

Actual Results

Team capacity does not accept the floating number for an individual weekly iteration after submit the changes.

Currently there is no known workaround for this behavior. A workaround will be added here when available
