Hi,
The issue seems to be caused by some custom CSS styled that you are using in the project,. I have tested the behavior in a similar scenario in our
Customizing the Time Slots demo and it worked correctly. Please review it and compare you CSS with the one suggested there.
Hope this will help you solve the issue.
