You can replicate this with a retract tower post-processing script with the said feature enabled. It works fine when you change retraction distance but acts up when changing speed. Some seemingly random values are displayed, it can also be seen in the G-CODE.
Here is layer 0 M117 command with retraction speed set to 5
M117 speed (5.0/5.0)
it seems to be fine for a few first layers, but at layer 8 it is
M117 speed F300
which just displays F300. You can take a look at the Gcode I compiled with this script, because I can't figure it out. also attaching a pic of a message that should be "speed 10" or something.
