In my purchase order, I added a PO Invoice, it's got a few items in it, quantities and costs all added. My subtotal is appearing as £1. The tax and total are correct but the subtotal is wrong.
I have also noticed that if I click on a quantity to edit it, it auto reverts to the cost of item. I've done the usual, tried a default theme, disabled plugins etc. Here is a short recording: https://www.gavinwillis.co.uk/wp-content/uploads/2026/03/ScreenRecording2026-03-31at3.00.01pm.mp4
