Assuming you are using P3D5, the problem is your .INI file, which must have been made for P3D V4, using custom textures, because an operator called "SCB" doesn't exists in GSX.
Before the update, this won't cause any problems, because jetway logos were completely disabled but now, since we added multi-liveries back, if an .INI file contains any logos, they MUST be one of the stock logos included with GSX, because in V5 custom textures are not supported.
We are working on an update that will check existing .INI files and will automatically ignore any logos for operators not included by GSX but, in the meantime, the only way to fix it is to edit the file and remove all lines containing
jetway_logo = xxxxxxxx
Unless they contain a name of an operator that does exists in GSX.
