[CLIENT] Negative Influence points? (picture included)

I have never encountered this problem before or thought it possible but I have negative influence points. I don't think I need to say anything more than that but here's how I magically achieved a negative amount of influence points.

Steps:

1. I went into my purchases and looked for the champion Elise.
2. I clicked the refund button in order to get back my Ip. (please don't hurt me if you like Elise I just wanted a different champion.)
3. Exited out of the store and opened the tab 'Champions'.
4. Scrolled down to Xerath (influenced by Febiven's crazy game) and bought him with my newly refunded IP.
5. Exited the summoner profile and looked at my ip balance. It was -590.
6. I was extremely confused and even tryed to scrub my screen thinking the negative sign was a smudge.
7. I just quit league and re-logged.
8. My IP is now 4210.

In conclusion, the problem has fixed itself but I thought it might be nice for Riot to know that there is a little glitch in the client. Love the new season guys and I hope for many gg's!
