referenced effect from preset inside several cues

This is expected behavior. Presets do store effect data, but the effect data is not referenced in e.g. cues. 

Think of presets with effects as delivery method that puts values in cues the moment you apply it, rather than a traditional referencing preset.

This is super confusing and a bad design choice in my opinion. I honestly think it would have been better to simply not allow effects in presets at all, they don't mirror the expected behavior of referenced data, so it's of niche use and causes confusion like this.

Hello,

what do you suggest to do ?

I need to store an effect somewhere with its channels parameters like rate, size, etc… to use it in several cues and beeing able to modify the effect parameters once and have the modifications effective in every cue without having to edit each cue on every effect parameter change.

If you use and effect in a cue and do not modify any parameters, and re use that effect then it will reference it in all cues. Anywhere that data can be modified such as size and rate, the numbers turn red and then can be saved in to the cue at that size and rate. If you have an absolute effect that references things like CP of FP and you modify the CP or FP then the effect will be change in all cues it is used in.

EG effect xx is a colour effect made uop of green and red. If you change the colours to Red and blue then all cues that reference that effect will change to the new colours.

You do not need to save the effect in a preset to make it behave the same in cues. 

I hope this helps you a bit.
