[MDL ED] Entities into Items

[The chaser]

on the topic of items I have run into a little problem myself and might as well post it here:

I have created an item for a mod I'm currently working on and set the settings in model editor exacly like an item from the original game. It shows up ingame,glows like an item should, and the interact hand icon appears when you aim at it. But for some reason you can't pick it up when you click on it. I tried placing the entity I had used as reference in the map as well, and it picked up just fine. Any idea what I might be missing?
heres a screenshot:

That must be a image problem: It happened the same with me. If you don't have an image for your inventory (or it doesn't work) you won't be able to pick it up.
