In setting up the owners did you use the Capital Accounts tab, if yes, then are the expense claims showing up under Capital Accounts (do a Capital report), if yes, then you can’t actually mark that expense claim as cleared because of the way Capital Account - Expense Claims are processed by the programme - read the topic below
Therefore to repay the owner’s expense claim you would :
Cash on Hand - Spend Money - Account = Capital Account - Owner - Drawings.
This has the effect of reducing the capital account as if the expense claim had been paid.
