You'll have to complain to Adobe about problems with Adobe support. This is a user to user forum.
You can have several movies linking from the same main menu (assuming your menu template has links for several movies). Just put put your movies one after another on the timeline -- with a stop marker at the end of each movie and a main menu marker at the beginning of each movie (and a few seconds of black video between them so that the markers aren't too close together).
How exactly you set that up depends on which version of the program you're using and what your level of skill with the program is. It's not likely you have Premiere Elements 14 since the current version is only version 12.
I do show you how to add several movies to the same disc in my Premiere Elements 12 course at lynda.com, by the way, if you're interested.
At the onset, this is not Adobe. This is a user to user forum.
Since there is no Premiere Elements 14, I am assuming that you are working with Premiere Elements 12 (the current version) on Windows 7, 8, or 8.1 64 bit.

If you need clarification on anything written, please do not hesitate to ask. Can we assume that you are planning for burn to DVD-VIDEO standard or widescreen format on DVD disc? Stop markers will function in the playback of that format. But, stop markers will not function in the playback of Premiere Elements burn to AVCHD on DVD disc or Blu-ray disc format on Blu-ray disc. Also, reminder, each movie on the main menu cannot have its own scene menu.
