Cannot modify color

Hello everyone, today when I was packaging the app, I found that the number of my extensions exceeded the limit of the free version. So I found a way in the community and deleted all of my extensions

This may seem like a great thing, but in fact, the color of the deleted aia cannot be modified after importing it using this method!

Whenever I click to modify, he will prompt me with the following picture

What should I do? Please help me
