Sub Bump Holding Value?

i am having a problem  where i have 2 subs set up on 2 faders and if you hold them down at the same time and let them both go at the same time one of them will hold there value until they are bumped again and if you want to recrate the problem here are the steps to recreate it 

open a new show file 

patch any LED fixture i used a elation seven par 

record sub 1 as all red 

record sub 2 as all white 

and then change down time to 1 sec

then map those submasters to any fader 

now when you hold down bump on fader 1 and then hold down bump on fader 2 and let them go at them same time if you look at then channel values will not release 

the oldest software this bug is not in is 3.2.9.16 

i am running a Eos XE20 

any help with this would be great
