no icons for items in base editor

For about a year and a half I have had a problem. When I use base editor to place an item, for the choice boxes of what can be placed all I get are white boxes, no pictures. Luckily I had done a lot of base construction for my first year, now the stuff I want, and dont care to slam much in besides teleport base stuff. Still, it would be nice to have this working. Anybody know a fix?
