If you click on delete, the entire thing will delete and all you will be left with is the rest of your models excluding this one. Updating the model has always worked, but it looks like theres an issue going on at the moment. I get the same too.. What I did to work around this is I uploaded the model as if it we're a new model and the 3d view showed up fine, but updating an existing model is where the issues at for right now...
