If there are more than 99 duplicates (like blank lines) it won't show those and must have at least 3 repeats. Modify if you need to.
Look for lines numbers that are relatively close to each other. Notice 4: Paris (190, 199, 208, 217)
which aren't that far apart and it's repeating four times.
Also the first two show repeating
6: [ (181, 184, 187, 196, 205, 214)On lines 22149, 22152, 22155 we see it's stuck for a short bit 3 times repeating timecodes as seen in the screenshot above.
4: ] (193, 202, 211, 220)
3: 07:19:37.300 --> 07:19:37.300 (22149, 22152, 22155)
