You're fine. There's no stress on that area.
I did something similar on one of my bows. Strung it up, but the string must not have been completely in the string groves. I leaned it against the wall while I grabbed my shooting glove. Then it just sprung!!! Jumped off the floor, hit the ceiling and scared the crap out of me. In the end, I only had damage similar to what you have. The bow has held up well for several years after.
