Build Apps colors error

[#1]

Hi, after playing around with built-in navigation I faced a problem with colors - on some elements, all of the colors become transparent, moreover, "launch" option has broken, as it doesn't add a page index so you need to add it manually

On other elements all colors are visible

I was trying to duplicate the project or an element with broken color as well as turn navigation back on - doesn't help, any advice?

Turns out it somehow deleted my custom color for cell's background, when I created the color again with the same name it helped
