New tanks having Issues?

I just bought three new tanks and wondering if anyone else is having serious issues with them.

At first I wondered if it was the new preform software, and the white resin, and the complicated models I have tried recently… then I went back to preform .9, the butterfly, clear fluid and a new tank and got even worse results…  just a thin base with a couple stubs and no supports… just more clumping in the tank that needs to be cleaned up (and probably hurting the tank silicone)

frustrating to spend more money thinking things would be better and now not doing anything right
