Snyk security check problem due to license

Hello,

My company uses a company called "Snyk" to do security audits on our software. It scans for vulnerable dependencies, problematic code, licensing issues, etc. It is showing a "medium level security issue" due to the license XLParser uses:

I'm not sure why it's giving a warning about the MPL-2.0 license, nor do I know how to fix it. I just thought I would bring it to your attention in case you wanted to fix it. Might be worth looking into.
