Amounts are changing at Paypal Point

Strange one.

We’re a charity for children with disabilities and hold events. We do this monthly and I’ve been using this system for over a year now with no problems. I’ve set one up to be released on Wed 7th Sept but on test bookings, the prices are changing at the Paypal point.

– One ticket no matter the price seems to work.
– Multiple tickets UNDER ￡9 seem to work

`LOGGED IN ADMIN USERS
1 adult at ￡5 CORRECT at ￡5
1 adult at ￡10 CORRECT at ￡10
1 adult at ￡10 and 1 child at ￡4 CORRECT at ￡14 (Don’t understand this one as it is not following the format)
2 adults at ￡10 INCORRECT at ￡10 (should be ￡20)
1 adult at ￡5 and 1 child at ￡4 – CORRECT at ￡9
2 adults at ￡5 each – INCORRECT at ￡5 (should be ￡10)
3 adults at ￡5 – 2 children at ￡4 INCORRECT at ￡9.01 (should be ￡23)
2 carers at ￡3.50 and 3 disabled children at ￡4 – INCORRECT ￡7.49 (should be ￡19)

I took a screenshot in PayPal and what it seems to be doing is adjusting the amounts from ￡5 for an adult to ￡1.67 for an adult at that point. NO idea why!

Also tried removing logged in users and admin access.

I’m not sure when this started as our Aug event was Free and the Sept event was fully booked by beginning of Aug so certainly in the last couple of weeks however.

If you think it is the latest update, can someone maybe advise how to roll back as I need this sorted by Wednesday ??

Other things to note:
– I used to be paid PRO membership. It ran out 16th Aug unfortunately ??
– It is also doing the same thing on the Nov and Dec dates which are also set up
– I have tried the WPBug plugin (so basically removed all the other plugins and theme) – but only tried it for me – not the whole site.

The tickets are not live yet, so you need to be admin to book but wondered if anyone else has come across this issue and resolved it. Looked through forum and couldn’t see any.

Any help/advise massively appreciated! Even if it is just how to roll back. Thank you.
