Mp3tag v3.27a and v3.28 version, regarding WAV file Tag settings, even without modifying any information and simply saving the file, each save operation increases the ISFT length of LIST by 1 or 2 0x00 bytes, with no length limit. This is an unexpected issue.
Please address and improve it.

Thank you!

Many thanks for your bug report. Can you share one minimal example file where you observe this happening?
I tried to reproduce what you're describing with an example and can't make it to happen when saving the file.
