Keyboard acting up

[MtKnttu]

I have had my new Corsair k70 (not RGB) for almost 6 months now after I received it as a replacement for another k70 I had to RMA. Just today, the numbers on the top row of the keyboard have stared acting very strangely, putting in characters that I didn't type. It's very hard to describe, so I'll just try and demonstrate it here by pressing each key once.

Using the numpad (which isnt affected):
1
2
3
4
5
6
7
8
9
0

Using the numbers on the top row:
1234567890-
234567
34567890-
456789-=
56789-=
67890
7890
890-=
9-=
-=

I have already restarted my system, and tried other keyboards, and only my k70 has the problem. Are there any solutions other than an RMA? I don't want to have to pay more money to ship another broken keyboard back to corsair.

And now, after doing nothing, It's fixed itself. I have no idea what's going on.
