Possible problem with credits for one actor in successive episodes of a TV series

I've been correcting the credits for successive episodes of "The Old Curiosity Shop" (1979) tt0227938 as someone posts them on Youtube. I've noticed that the credits for one actor/character Granville Saxton (Dick Swiveller) are still showing as Pending, whereas all the rest of the corrections were published within an hour. Could it be anything to do with the "ooo Matronnnn" nature of Dick Swiveller's name (blame Charles Dickens!) or is that a red herring? The submission IDs are: 250824-194000-474000 (episode 1.1), 250825-143705-785000 (1.2) and 250826-135456-681000 (1.3). If it just needs more time, fair enough, but I wanted to alert you in case there is a problem which is preventing the changes from ever being processed, no matter how long I wait. I will probably be submitting future episodes roughly once a day, depending on how frequently they are uploaded to Youtube for me to copy the credit orders. Can you set the visibility of the thread to "Public". Is there some reason why several of my recent postings have defaulted to "Private"?
