AMM Channel Pre-Fader sends do not work

Hi, since the 2.01 update i´ve got send problems with channels which are linked in an amm group. when i send them pre fader to an aux or matrix the amm still levels them. the only workaround which i´ve found was to set the source point of an aux higher than the post delay. did i miss some new settings or is this bug? i use the avantis as a brodcast console and need this prefader function for icom.

the problem occurs in both amm modes and the follow fader is on
