Can I Change my FBA Store Name?

I recently began the process of starting an FBA store, but found that the store name I chose would not be shown in full. I guess I’m limited to so many characters? So yesterday, I decided to change the name to make more sense. But, I haven’t listed anything yet, and wonder if this will cause any glitches once I do start listing in the coming days?

Also, the name change is not yet reflected at the top of my seller account, but IS seen in my account info. So I’m confused, and don’t want to cause any broken links, and the like.

Was I able to change the name like I did? And how many times can that be done without causing issues?
