Pan/Tilt effects with no basepoint bug?

have cue list with 2 cues:
1 cue: tilt effect with “Sine” curve
2 cue: same effect with “Sawtooth” curve
When I create effect in 1 cue I check “Free - uses any basepoint” and “Don’t use own basepoint”.
Everithing works, except 2 diffrent curves in different cues. So I can get only “Sine” or “Sawtooth” in both cues.
If I uncheck “Free - uses any basepoint” - everything is working correctly.

this issue occur only if I provide basepoint by fader (cue list with 2 cues with positions and crossfade on fader)
