That one looks correct. I have seen some where they deliberately leave last sentence (usually advertizing) to be displayed until end of file.
Really odd problem, does it show the same way if you play converted disc in computer?
Are you just deleting the string itself and leaving the line number and timestamp? Because i delete the advertising all the time and have zero issues (when testing with vlc at least)
The trick is when removing the advertising if it appears during the early video is to LEAVE the subtitle number and timestap but replace the text with a single space. If you leave the line number and timestamp and delete the subtitle text its sort of an "empty line" that messes up the track ordering and display. I found that out a long time ago. Subtitles would stop appearing after the "advertising" moment. The solution was to leave the line number and timestamp but replace the text by a single space. Because removing the line number, timestamp and text would trigger the need to renumber the line numbers after the advertising text. Since a subtitle track can easily have 3-400 lines for an episode, that's too much work (for me).
Since spaces arent visible on screen but are still valid "text" subtitles continue to appear normally. The advertising that's often at the end of the file too, i just delete everything. Line number, timestamp and text
Can't say for sure here that's what's causing the problem, just a thought.

Just to put in my two bit: When I have to deal with subtitles which contain first and last line of advertising, I would remove just the text on the number one entry and delete everything on the bottom. So far I've never had any problems.
Have you ever tested this issue on another player ?
