Trouble reclaiming ethanol with Xact Xtract LM2

Hi Everyone!
I was wondering if anyone else out there has experience with Azoth Xact Xract LM2? My issue is that I can’t seem to get 100% of ETOH back after doing rinse cycles, is anyone having similar issues?
Thanks and sorry if this has been asked before, I couldn’t find anymore intel so went on here.
