customer view does not display the amount spent

[OptimusBain]

Good morning,

There is a problem with the customer view in ACP. It does not display the total amount spent by a user. It does show it on most users but this user in particular does not. I think I saw a couple more the other day. 

See the attachment. The user has already spent 20 EUROS, but that amount is no shown. The username is: rezoner

I need your help.
Thanks a lot

This is because that invoice was marked as manually paid, and there is actually no transaction alongside it. So the user hasnt actually spent anything with you there.
