Fabfilter Pro Q3 issue no processing

Dear community,

we have noticed an Fabfilter Pro Q3 issue during soundmixing on Pro Tools Ultimate 2025.12.2.

Sounddesign was merged from multiple sources (Sounddesigners) and the Sounddesigners has used three different typse of Pro Q3. During Mixing, we had issues with v3.27 SD to work properly. Sometimes no processing was occure or on stereo tracks, only on one channel was processing. Has anybody noticed the same or similar issues and if so, what was the solution to solve it? Our specs below.

Many thanks in advance

Markus
