Hello giancarlo,
To be able to help we need to have more information about the exact problems that you experience.
Please open a support ticket and send us the following:
- Sample project where these problems can be reproduced. Make sure that the project can be run locally.
- Reproduction steps / screenshots of the problem
- Detailed description / edited screenshots of the desired behavior.
Once we receive that, we will do our best to help.
Regards,
Georgi Tunev
