Filter problem

Hello everyone,
I’ve been noticing some digital stepping artifacts on the filter with certain settings. In this case, I use the low pass filter with the resonance at 100%, Classic Distortion at full gain an 100% wet. When I start turning the filter down I get these odd glitching artifacts at the first 25% of the filter sweep. Strangely, I try the same settings on the Minifreak V and these artifacts don’t appear most of the times, but sometimes they do.
I’m puzzled since the filter on the hardware is analog, yet I keep getting these noises but not on the software which hosts a digital emulation of the analog filter.
I’ve made a short video demonstrating this issue, first with the full patch and later in the video with both Oscillators at 0. Here’s the link:

I wonder if this issue could be fixed with some sort of firmware update or maybe there are some settings in the Minifreak system that I could change in order to prevent this from happening.
Thank you in advance!
