Alright, I think I understand your problem now, Nirvaeld.

It's not Shift+ +1~4. It's Shift+ THEN 1~4.

The difference is on the first combination, you press all 3 of those buttons at the same time, while on second combination, you press shift+, take your fingers off both shift and the THEN you press 1~4.
