I have two transactions that I need to delete but the delete “X” is greyed out. There is a cloud symbol which means that these transactions were “imported from a feed or uploaded statement” they weren’t as this is a petty cash account!!
The transaction could also be from a journal. If you click on the Tagged button, it should reveal more information, such as the name and link to the journal.
Anything where you split a “something not on the list” to more than one code will become a journal, as will anything tagged as a salary payment if you have “post net wages to balance sheet” turned off.
