Main account 113000 is in Account structure MA-PGU

If I select all FinDims on an FTI line

I posted the FTI. When I view accounting and it takes me to the subledger journal, it correctly shows only PGU, as per the account structure. This seemingly ignores the other FinDims populated.

Is this expected functionality? To allow me to post an FTI with FinDim values selected that don't adhere to the account structures? When shown on the ledger account it is correct, but I find it odd that on the FTI there wouldn't be an error message on posting? Am I missing some config? Even after posting, the FinDim values selected (all populated) are still there.
