Load a style puts the time signature upside down

GIT commit 6eb58d5 / Windows7

1) "Untitled" score
- No need to change any parameter to receive the issue, so:
2) Format -> Save style
3) Save/Close/Reload
4) Format -> Load style

Result: the time signature is upside down

• Other aspect: by changing the scale (X or Y) in Inspector, this time sig disappears.
