Doepfer

I own a Doepfer A-190-8 midi clock sync module, and a Mutable Instruments Grids drum sequencer.
For some reason I cannot get them to sync properly to the song tempo in Cubase.
Or in other words: the tempo sync ok, but the Grids module doesn’t start in time with Cubase. 
I’m not sure if it’s a problem with the Doepfer module or the Grids module, or if it has something to do with the way I’ve set the communication up between them.

I recorded a video illustrating the issue. Any help is greatly appreciated as I’ve had this issue ever since I first bought these modules.
Best regards (and happy new year) from Nicolaj.
