How to unlink a subgroup total for yearend adjusting entry on general journal

SUGGESTED

I am entering the yearend adjusting entry through the general journal and I've had to unlink two accounts already to be able to use them however there is one that I cannot unlink. It is a subgroup total account and I've tried Sage live chat and unfortunately they weren't able to help me. Is there a way to be able to either unlink this subgroup total account (have gone through setup  and settings etc.) or some other method to make this account usable so I can enter my adjusting entry? Thank you.
