some time last week when i went to go invoice, all of my flat rate line items were acting like by the hour or unit line items. it used to only have flat rate, no QTY or HOUR option while invoicing, and now all of them have suddenly stopped. There is no point in a flat rate option if it is not set up as a flat rate. I don't know why this was changed as this causes some pretty big issues with billing if you were to accidently change the qty on a flat rate. It has already caused issues. Flat rate needs to go back to being billed as a FLAT RATE
