I ordered a new bella tank from the last batch and received it yesterday. I have 2 other ones that I ordered some time ago and the bottom caps are completely flat on those (where the carto goes in) and the new one I ordered has a completely different shape. Almost like it is "rounded" where the carto goes in. I filled 2 cartomizers last night and the juice leaked like a faucet out of both of them on the new tank. I've NEVER had a problem with the other 2 I have and use them daily. I've been trying to figure out if it is something I did wrong, but I'm not filling them any different than I ever have so I can't figure it out. Anyone else having any issues?
