Overlapping advert on My Portal

[#1]

Sooo, I was navigating around the various tabs available via My Portal...

....and https://www.plus.net/my.html?action=view_transactions&s=0 shows an advert for your mobile offerings, but it's overlapping the text behind it:

The previous time I looked, which admittedly was about a month ago, the banner was further up the page!!

Very odd, I've just logged in on my account at that page and it's showing on the right hand side, just under the menu.

If you refresh does it fix it?

Snap!

I'm using Palemoon 27.1.2 and a forced refresh doesn't fix it.

Using Waterfox 51.0.1 the ad is where I expect it - at the top RH.
