Backend Dashboard scroll down error

Hi,

Just want to make a report.

I see a shaking, jerky movement when scroll down to bottom of Easysocial backend admin page.
So far I've found this on backend admin Dashboard, Profile Types, Albums, Polls, Reports & Stream.
I've tested it on Microsoft Edge & Chrome so far and it appear in Chrome but not Edge.

What I did was;

1) Made a fresh install of Joomla 3.7.2 with sample data, multi languages (Arabic & Malay, default to en-GB).
2) Install EasySocial 2.0.18
3) Go to Easysocial backend dashboard - Languages and install Arabic and Malay.

This is just a test site. (see at 'Additional message' for access info to this site)

Thanks.
