Version 2.2.x introduced Marani IIR filters and a “FIR output sample rate” parameter, which is different to the channel sample rate used for IIR and gain & delay. The “FIR output sample rate” parameter broke the Wavelet view for cases where the “FIR output sample rate” is different to the channel sample rate. We are currently working on a fix. (The filters are correct; it’s just the Wavelet display that is broken.)
I’d suggest confirming that the channel sample rate and “FIR output sample rate” parameter are the same. If they are the same and you still see problems with the Wavelet view, for now please downgrade to the most recent 2.1 release; 2.1.11.

And if you have time, can you email us your system (fds) and project (fdp) files.
