Thanks for contacting support, I’d be happy to take a look over this issue with you. I have tried to reproduce what you’re experiencing by input a recording start date of 2001 on one of my albums and I have had no issues doing so. To better understand what’s going on here, can you please provide:
A few screenshots outlining this issue from your end?
Is there a specific year that you notice not being able to input correctly or is this for all years containing 0’s?
Does this issue affect only certain albums or all library albums?
Is there anything unique regarding the format of these affected albums? Are the albums all MP3/AAC/FLAC?
Please let me know the above information when possible.
