When I load a style I have saved from another lead sheet, it doesn't seem to apply correctly to the new lead sheet. I say "seem" because, for example, the distance from chord symbol to the staff says 1 both sheets, but it is much further in one than the other. I'm using 2.1.0 on my MacBook with 10.13.3.
Chord symbol position is affected by two different settings: Style / General / Chord Symbols, and Style / Text / Chord Symbol. Also, any given chord symbol might override this via a manual adjustment that would be visible in the Inspector. Also, in releases previous to the current 2.2, load style will often require a "Reset Text to Style" (in Inspector) to pick up the text style changes. Update to 2.2 if you haven't already.
If that doesn't help, please attach the score you are having trouble with and describe the problem in more detail, and we can try to assist better.
