Damaged goods. You should be able to send it back for free if you documented the problem when you opened the package.
Depending on how you intend to use it, the gel might be okay. If I was using this on a stage in a spotlight, I am pretty sure it would burn through prematurely. Gel has to lay flat in the holder in order to resist the heat. Air flow is key in that application. In a regular light fixture with glass to shield it from heat it might be all right.
The decision is yours but, if it was me, I'd send it back.
