Effect Speed on chosen Master

If i change the "effect speed" of my cuelist behind my chosen master with the encoder wheels, it will be faster or slower as 100%.
But if i give the default effect rate with 100% again - it will only stay at 100% until I reboot my console or record one cue more to this list. After reboot or record a cue, my Hog switch back to the rate i - or the guest operator - changed the !first! time touching this tool.
It´s my fault or a bug?
