Subtitles bug still there in B5

As reported on previous DR17 betas, when adjusting values in style tab of inspector for subtitles, the values in all the boxes do not reset to default number value when reset icon clicked. The actual subtitle text does get reset, but value boxes don't reflect that. Anyone else confirm that or can BMD guys confirm the behaviour I'm experiencing?

Can anyone at BMD confirm this behaviour on subtitles please (Windows 10)?

You should make new entries to existing threads rather than keep making new ones that say the same thing

Still present in b6, as described on previous posts.
