Unable to Edit Form properly after Applying Theme

Hi, When I pick a theme from the new theme store, install it into a form I created and personalize it - such as width, fonts, background colors etc.  I can then save it.

However, if I have to edit the form - say change a font size. I cannot get back into the theme without re-installing it into the form, which deletes all the changes I made.  I've tried clicking on themes in the edit form section - it brings me to the theme I used, but I can't edit anything.

So, my only option is to click on themes at the top of the screen, which makes me re-install it on my form.

This is EXTREMELY frustrating.  How can I edit themes without having to start over?

So basically you mean that you are applying a theme to your form at which point you cannot edit it properly if you want to change something in it for whatever reason until you restart and reinstall the theme you originally applied after making changes to make it work.

Is the Christmas Type Theme that you have applied on it the one that is giving you this issue? Or?

I've tested this below I tested the font size putting it at 24px separately on my end but I seem to be unable to replicate a problem.

What Browser and Browser Version are you using? Can you try another browser to see if it'll work?
