我这里是正常的，新贴图也没有改变这部分内容

Hey, are you talking about the file name that records the airplane customization options?
How exactly does it affect things? Is it the ATC call sign or the configuration reading?

For example, in livery.cfg, "atc_id" is defined as "B5468". However, when selecting a livery in the game, there are three options (registration number, call sign, and flight number). If I fill the registration number as "B-5468", PMDG seems to create a new aircraft config file to match "B-5468", unless I enter "B5468" and it reads the pre-set configuration file which you provided.

Okay, thanks for the info. I’ll make changes in a future livery release. But since this might affect some users’ custom setups (PMDG's configuration reading is really weird—some people can never get it to load automatically, and modifying it makes the game treat it as a new livery, which can cause saved settings to be lost), for liveries that are already out, I'm afraid you’ll probably need to manually tweak the settings in the two livery files.
