That's just Revan's gender and ending weren't properly decided, it was always LSM I think, now it takes the one of the 4 it should.
Nothing to do with your issue, even if an outdated .dlg would overwrite it (you would just be stuck with the 3/4 chance of incorrect Revan again).
@ EELON; Not really. Actually, it would probably more likely to get issues when using TSLPatcher with mod conflicts as it may start to skip TSLRCM files (which can give big issues), while with the installer it would just overwrite them.
And there are FAR too many changes in TSLRCM's dialog.tlk (English version only) to use TSLPatcher to modify them all.
