Hello, we erased some periods that weren't needed to start customizing or own setup, but now we cannot add any more Periods.
Here is a screenshot with how School -> Periods look: https://upload-image.rosariosis.com/gallery#MaYBH35s/rJzgOwyg.png
Any help would be appreciated.
Thank you for reporting the issue.
This is a regression in version 4.7.
The fix (to add new Periods) is available in version 4.8.1.
Thank you very much, all fixed now!
