Plugin Metadata Gives Wrong Versions

[Spirrwell]

Hello!

I run Linux Mint 20. I've built Qt 5.15.2 from source as well as Qt Creator 4.13. I'm trying to build/debug an old Qt Creator plugin. The generated JSON file for the metadata shows version 4.13.3 for it and the dependencies.

However, the built SO file of the plugin shows up as version 4.13.83 in Qt Creator, and so it won't initialize. Hex editing the metadata version inside the plugin's SO file does allow it to load. Is there any reason why the version ends up wrong?

Any help is greatly appreciated!
