You’re not alone, this is bad, on latest firmwares elektron payed very little attention to MK1 - maybe in Sweden they sold all the mk1s? 
and even after some feedback, one year has passed and no legacy option (yet!!)
Please write to Elektron, I think they are working on it and they might be able to help you.
edit: until you get a response, try using [FUNCTION]+Knob to snap to integer values. This is quite difficult, the encoder speed will be VERY sensitive.
