Can't add labels with . in it
When you add label with . the UI doesn't show that it's illegal character. Although why it should be?
Steps to reproduce:
1. Create milestone
2. Create issue
3. Add label to issue
4. Add label with . in label e.g. MKOv.12
5. Add label to iissue
6. Go to issues
7. Can't filter with new labels after label with .
9. Labels are gone
support for dots in label names was added in https://www.perforce.com/products/helix-teamhub/release-notes#deveo3180 Deveo 3.18.
