Track.AdditionalFields.Clear() reporting false "key not found" warnings at save time

[kitsumed]

File Type : mp3
Format : ID3v2

*Note (Same sample file as #315, can resend if needed)

Issue:
When saving the new metadata after calling Track.AdditionalFields.Clear() ATL does remove all of the fields (TXXX in this case) but also throw warnings in the console for each key name that read out as 'Field code [KEY-NAME-HERE] cannot be deleted because it has not been found on current TagData.'. LOCATION : 'C:\Users\<hidden>\AppData\Local\Temp\file.mp3'. Warning that does not make sense as all of the key where still deleted.

Sample code:

// Load the file in ATL
Track audioTrack = new Track("file.mp3");
audioTrack.AdditionalFields?.Clear();
bool wasNewMetadataApplyed = await audioTrack.SaveAsync(); // Warnings are reported here

*Require that the ATL loggers delegate is configured to see the warnings

Thanks for your feedback. This is a specific issue that arises when ATL rewrites tagging systems that have a fixed set of fields and therefore do not support additional fields (in that case : ID3v1).

There's no actual problem; these messages shouldn't even show up.

=> Fixed for next release ✅
