Okay, I understand what’s going on I think. (I can fill you in if you don’t want to wait to hear back from @kathan).
When you place the material on the honeycomb tray, you want to pull the material forward so that it covers the honeycomb grid part of the tray at the front. Don’t push it back so far in the bed. Then the design will completely fall on the material.
There is an overlay on the screen that prevents you from placing the design where the head can’t reach. (In other words, the left side is blocked deliberately. It’s done that way to prevent you from wasting material.) You will still have a full 19.45" by 10.95" of cutting space, but it does not fall onto the left inch or so of the actual material.
Does that explain it? If you want to get the most use out of your material, always place your designs as if the origin for the material is at the lower right front corner of the gridded portion of the tray. Build out from there with your layout. It will leave about 3/4" of uncut material on the left side, 1/4" on the right side, and about an inch at the top. But you can flip that over and use up the uncut strips for small cuts like Honeycomb pins.
