Payment Methods

We have big issues with the AMEX button on Pabau the girls on FOH use it but it never records so when it comes to doing banking etc i have to go through and find the AMEX payments. I created a new AMEX payment method option that does work but i am unable to disable the original one so it confuses the girls especially when it is very busy. I have had to rename it USE THIS ONE so they know.
Not sure why the Amex button is not working but also frustrated that the replacement option i have added is still not easy because i can’t disable anything.
Thanks Pauline
