Wrong customer being linked to invoice payment

[SodaStar999]

Hello, I'm having difficult finding any mention of this problem elsewhere so maybe the community can help!

In the 'Invoices' overview, the correct customer names is listed next to all invoices.

However the following error is occurring for several invoices:

- Correct name listed at top ('Invoice for xxxx')

-- INCORRECT Customer Profile linked underneath 

- Correct name/email listed under Customer (beneath payment details)

As a result, multiple payments are being attributed to the wrong customer. Any advice welcome!
