Not at all usable – Do not use

I installed this plugin, at first it appeared easy to customize and work.
After I have finalized everything, I saved this as a template. When I came back after sometime, there is no trace of what I saved.

I thought, may be I made a mistake. This time, I just tested it with few changes and again it did not save. When try to publish, it pops out some comma separated settings (It is not a WP short code), and there is absolutely no idea given on what to do with this text.

There is no documentation and demo page is not working.. Totally useless, wasted my 2 hours on this.
