Doesn't happen, and nobody else reported it.
Have you perhaps applied the latest update without having applied the previous major update ? If not, or you aren't sure, download and install the latest Stand-Alone Addon Manager (download it again, even if you already have a copy), and install that one.
If the problem still doesn't go away with the current Addon Manager, please report exactly the following:
- Airplane used
- Airport used. If it's not default, identify the scenery and, possibly, which AFCAD is used
- Gate selected
