awesome-pricing-tables-lite-by-optimalplugins

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.
