I am having the same issue w/ tws in certain energy contracts, I guess the expiration logic is incompatible. It seems that the quick fix is to use TWS 890.
NT site points to download 892.7 = problem persists
IB site 894 latest version = Problem is not addressed yet
IB site only gives access to prior 2 versions of TWS
My question is if we should use 890? do you have a link to download?
and if so, is it safe to assume that IB no longer supports that version?
