Textures of billboards staying in the game

I started editing the map with CodeWalker. First I deleted the advertisement board above the entrance of the Pacific Standard Bank. In CodeWalker the advertisement seems to be gone, but when I load in the ymap on the server, the frame behind is gone and the texture of this flow advertisement is still there. The same problem applies to some other billboards. I couldnt find any thread of this. Does anyone know how to fix the issue or a good work-around?

Hello,
I mean this is the wrong topic but:
The textures of the billboards are in a much larger box. so if you have more billboards in one area they are mostly combined to one “prop” you have to move things around to find this.
