WHen doing a 50 credit journal entry to a gl account labelled"other current liability" I expect the balance to go from -200 to -250 but it goes from -200 to -150??Why?

I'll help ensure you'll be able to get the correct balance when recording a journal entry in QuickBooks Online (QBO), @unit618.

An accounting journal entry is the written record of a business transaction in a double-entry accounting system. Every entry contains an equal debit and credit along with the names of the accounts, description of the transaction, and date of the business event.

A debit is an accounting entry that either increases an asset or expense account and decreases a liability or equity account. On the other hand, the credit increases a liability or equity account or decreases an asset and expense account.

The problem you've encountered may happen if the amount isn't entered to the correct accounting entry (debit or credit). As of now, I'd recommend re-checking the journal entry created and ensure to enter the amount to the correct debit or credit.
