MIssing scroll bar in Azure Auto ML Data Assets Screen

This has just happened today, the same process worked fine last week. When I'm creating or updating a data asset in Azure Machine Learning Studio, I can move through the first few screens - data source, data type, source storage type. But when I get to page 4 - query, I paste in the query and it expands the screen so the next/review buttons are no longer visible, and there is no scroll bar to move down to it. I've tried on multiple browsers and difference tenancies, a colleague is having the same issue as well. Even if I choose a more basic query to allow the buttons to be visible, when I move to page 5 - schema, I get the same issues.

In the first image below the next/review buttons are greyed out awaiting the qeury to be entered. In the second image I've entered the query (blanked out here) and the box has expanded but there is no scroll bar to move down the page.

Has anyone come across this before or is anyone else getting this issue?
