Bug in export of subtitles - always changes frame rate

[CrawlingCha0s]

When I load a BD .sup file with no options checked in the conversion options dialog the frame rate is correctly detected as 23.976. I then immediately export the file (no options checked). If I then reload the file I just exported the frame rate is now 25 (or whatever the Target FPS setting was in the conversion options dialog on loading the original file). This happens even though Change Frame Rate checkbox is left blank/unchecked. The FPS is not being mis-detected as tsmuxer and other tools show the same change in frame rate for the exported sup file. The only work around is to explicitly make sure the Target FPS is set to the same as the Souce FPS even though the box is not checked. Seems the unchecked state of that option is being ignored in the current version 5.1.2. OS is Windows 8.1 Update 1 (64-bit)

I have same issues, time codes are wrong. I find that setting 25fps in .SRT file fix a little the problem, but times still are different in SUP from original SRT (but just in milliseconds, almost inappreciable)
