Groove Agent SE 5

hey guys, i have a little problem any help would be aprectiated

for some strange reason Groove Agent SE 5 on cubase 10.5 wont let me change values of each sample. im not new to groove agent and i know to use layer mode and to make sure SEL is selected in the right hande corner. nothing i do seems to fix the problem.

i then downloaded the Groove Agent 5 trial and everything seems to work fine there but again when i try on the SE version it wont let me play around with the levels sepratly.

i did a quick search to see if anyone else is having this problem but seems only the people that forget to layer and hit that SEL tab have had this problem.

any help would be good as i need groove agnet SE to work.
