5D controller button come loose

[cagliostro]

I found the 5D button has come off in the transport bag I have. I think it's because I was using a 3D printer stick guard that of stress on it. Can I just glue it back on? I don't fancy being without the use of it for 2-3 weeks while I send it back to dji under warranty. I placed it back on with no glue temporarily and it feels a little different and higher and not as crisp. Any advice anyone? Thanks in advance for any help!
