From .sup to .sub/.idx using SubtitleCreator, problems with background!

[guest]

Hi!
I am using the latest version of SubtitleCreator. My intention is to convert my .sup file (from PGCDemux) to a .sub/.idx file.
However, I can't get rid of the blue background on my subtitles! This happens to every subtitle now and then. As you can see in the picture, there is a blue background on the text, for other parts of the subtitle, this blue background is transparent, i.e. not there. How can I get my sup to show no background when I convert it to .sub/.idx ??

(When I remuxed the .sub/.idx with the re-encoded video and audio, the bluebackground in the subtitles would show. I have tried to OCR, but these subtitles are really hard to create a character matrix for, as the subtitles glob together, and you have to constantly manually submit letters - for episode 1 a character matrix worked fine to create an srt, but for episode 2 (where now I'm struggling), I have to basically type out each sentence, as it globs together.)

Use BDSup2Sub,it will remove the blue background and save to idx/sub.

Nothing more to say other than BDSup2Sub++ might also be interesting (not Java, but C++ based).
