UI problems

There’s a word glitch with the user interface customer portal where my customer list is. I can’t seem to make the changes. I need to for customer information where I clicked to edit the names of my customers, and it won’t update or change. The other problem is the page that shows the invoice total for some reason it doesn’t show that it’s the amount I’ve chosen it always shows $0.00 it doesn’t affect what my customer says, but I want to be able to at least see what I’m charging them before I send them the invoice without having to go into a separate page.
