Product Service Pop up box width has changed

When entering an item the popup that appeared as you typde was a suitable width so you could read the products (the pop up overlapped the other columns).

Now it is very narrow, as narrow as the column, meaning you only see the first part of the description, all of which are similar e.g. "O-Ring" " as the item ID# takes up the majority of the width. 

Is it possible to change this back?

I've tried various computers, private window.
