I see some older mentions of similar problems but this seems a little different. I’ve reproduced this in a standalone library and design file…
I start with a MUI Select component in my library and create instances in a separate design file like this. Each label and value are set by Text properties.
I then update the library to slightly restructure the component. Each label gets grouped with another text layer that optionally shows a “*” if a new “required” property is true.
When I publish the library, I expected all the labels and values to remain unchanged… but, only some of the variants do… The funny thing here is only 1 reset. The last time I tried this, 3 of them reset. What is going on? (Ignore the error variant’s label’s color change - my mistake.)
