Which version of Picard? What operating system? Can you make the file available somewhere so a dev can inspect it?


Sorry I did not notice the reply notification email.

Picard Version: 1.3.2
Operating system: Windows 10 Home
Link to files (first one is the problem file, second file is from same album but works fine):


Can you try updating to Picard 1.4.2 and see if you still have the issue?
