If DeClicker finds more than about 500 problems to repair (I'm guessing the exact number is 512) it displays no problems at all. Pressing "repair all" seems to clean up the pops and clicks, so this is likely just a display bug.
Declicker will find this many problems in several minutes of most vinyl transcriptions.

Thanks. This bug has been written and should be assigned to an engineer soon.
