From looking at your point count, all the votes you have received correspond with your point total. I don't think your points where ever reset. However, what you may be seeing, is your 3 different point totals. For each section of the site (Pokebase, Battle Subway, and Meta) you have a seperate point total. For example, you have 52 points on Pokebase, but only 20 points on Meta. That's all.
