That seems similar to a problem I’m having, but for me its only with a certain multi-way arrangement. I don’t think I’ve seen it with a single switch (load only) arrangement.
I initially reported it in the v1.55-beta thread as I initially thought it was a bug related to that version but I have since then downgraded as far as 1.48 and still have the problem. I now think its something in the Inovelli’s 3-way-toggle sensing circuitry. It mostly works, but I think the sensitivity and/or calibration may need some tweaking
