For testing purposes, I have duplicated existing stats and then modified them but there seems to be an odd issue whereby the custom stat cannot be further edited nor deleted after while.
For instance, I duplicated VPIP and set the new name/title to VPIP2, set it to be not 'Protected'. I then edited expressions and colour ranges and then saved the new stat.
After a while (which means I've been testing the inclusion of the new stat in a HUD a few times), if I go back to Configure -> Statistics, the custom stat cannot be edited nor deleted anymore. The right-hand side window is grayed out for most of its content, including the Protected checkbox, which despite being grayed, is selected.
Is this expected behaviour?
What do I do if I want to delete these cutom stats?
