Matlab Compiler not showing Java option

I'm having some trouble trying to export a function from Matlab to Java. I'm following these instructions from the Matlab website but my problem is once I open the library compiler the only option that's showing up available for export is Excel Add-in. I've tried looking up for some option in settings or checking if Java was correctly integrated in Matlab but I don't seem to be able to find a solution by myself.

Any suggestions please? Thanks in advance, here's my library compiler view.
