Fx Rate change halts Fx

Just so I understand,

I have a cue in playback with an FX running
Hold Choose and turn the encoder to adjust the size
You are seeing the FX stop instead of getting bigger

I just tested this and I am not seeing this.
The FX size and Rate just increase but the fx never stops.

I did not try to adjust the size, I'll try to recreate the problem tomorrow, the desk is in the van now ;)

List on a playback with a single cue in it with an intensity effect on a few fixtures.
I did have other playbacks active with the same fixtures on HTP master with intensity @ full (fader @ zero)
The playback with the Fx in also as HTP master (fader @ 100)
Hold choose and turn encoder to adjust rate > Fx stops. (as if Rate would be 0 while it isn't)
I've had the issue on 2 different show files, both made from a new show, not made from a template show, on 2 different systems running 2.5 ( Roadhog 4 and Nano Wing 4)

Please send me the show file and a repro on how you are getting the FX's to stop.
