Does it matter if you open the cover from outside the block or from the tab in the block's UI? Does it matter what position the cover window is in?

[Epsima]

it is apparently very inconsistent, sometimes it deletes the items and sometimes it doesnt. I am talking about the tab in the block's UI, I've also tried it with multiple other machines and making it face towards multiple other directions with the same inconsistent behaviour. my theory is that the "delete item" function from NEI is interfering with the cover's UI..?

edit: there are no problems when opened from outside the block
