Impossible to say with a so sparse description of the problem:
- Which scenery you are showing there ?
- Which kind of jetways it had BEFORE you customized it ?
- Has this scenery the ability to switch between different kind of jetways ? If yes, how it's configured now, and is this configuration coherent with the one you originally made the customization with ?
So yes, even if you said "all my airports", we need ONE reproducible example, with a detailed report and, of course, a copy of ALL files involved, meaning the AFCAD you are using, and your customization file, so we can try to reproduce the problem because, being able to reproduce the problem, is the one and only requirement being able to fix it, assuming there is something to fix to begin with. But of course, we cannot possibly know until we can test it.
