Space after clefs in cues, start of line

image
As you can see, the space after the C clef is too big. The cue starts two bars earlier:

and there the spacing is fine.

Earlier in the part there is a cue starting at the start of a line:

Then the spacing is also fine.

I can solve this by using manual note spacing in engrave mode, but can the space after the clef be controlled globally?

Thanks in advance,

EDIT: It seems that the extra space is added when the clef is repeated after a line break. Same for all clefs. Bug?

I have the same problem. I think it must be a bug. It seems like the system break creates a gap after the clef change that is 1 space wider than the setting in engraving options.
