Hello everyone!
It's my first time using JEVENTS for Joomla.
I'm using:
- Joomla version 3.9.25
- JEVENTS version v3.6.13 Stable.
- XAmpp VERSION3.2.4

I have this issue:

I'm not able to create a new JEVENT menu, when I try to do it, I lose the SAVE and CLOSE buttons from Joomla.
Please see atached Images SCREEN1.PNG, SCREEN2.PNG ans SCREEN3.PNG.



The JEVENTS Dashboard is not working properly as well.

Your help will be apreciated,
Thanks
