Subform Layout Changed?

Subform Layout Changed?

Hi
We have a subform in one of out Potential layouts.  in december everything was fine, now that we have come back since last week, when a user edits all the columns no longer show and you have to scroll (see capture) - it is like the layout of the page has now been changed by Zoho as it has occured in in between sometime in the new year.

Can you please clarify? I have tried in Chrome and Firefox browsers and it isnt a browser issue

Thankyou
