Error adding and editing guides

Guides do not get added correctly. It seems that they are added at roughly where the timeline select arrow is, but it's always ahead of the game.

When I my position on the timeline is 7:01 and I add a guide, it get's added at 8:04! Further down the timeline the differential is much larger, it seems proporitionate.


I cannot reproduce, can you please give more infos:
-which Kdenlive version
-are you working on PAL or NTSC project
-does it happen on every project or only on some
