Symbols cannot be placed

Hello,

I copied the radial gauge symbol, and made a few adjustments. When i try to place the symbol on the HMI it opens the symbol page. The same is happing with the orignal symbol.  
I made a lot of symbols that did not have this problem. I switchted to the 2023.0 lts version of plc next engineer.   
Is there something i am missing?
