Keys not displayed randomly when double-tapped on modifier keys

Hello everyone, I’ve had a keyboardio model 100 keyboard for almost a year, I’m French and use it with the bepo layout. So far nothing to report but I decided to activate the modifier keys and since then, from time to time, when I type double letters tt or ss (on the modifier keys in my configuration), a letter is not displayed randomly.

I’ve tried configuring the timeouts, setting everything to zero and disabling the functions in the chrysalis settings, but nothing helps. I’ve also updated the firmware to the latest version available on Github and still the same situation.

Have you ever encountered this problem?

Thanks.
