Hello Usernestor-ale,  We can put a feedback request in with the product developers we have been advised that it is working as designed and similar to some reports in that a location can be added to a whole transaction however a class can split amongst many classes on one transaction and therefore does not have one class to put in account history which whilst not the overall reason in this section it is a factor, we can see you mention if you use a certain code on the transaction it does show. It is something which is as designed we have been advised I appreciate that column is there and you would expect it to pull through that detail. In this case for classes, it would be a case of running a account detail report from the reports section rather than using the bank account history to track them,
