Hello I am havin problems with my dct. So I fill up my tank directly on my pv by removing the drip tip and metal end cap . All goes well I fill it up but as soon as I put back the cap all the liquids comes up and floods the cotton end of the carto and im stuck vaping juice or having to remove some with a q tip . Also when I put the cap back on liquid oozes out of the bottom but once I wipe it it stops oozing . What's going on I'm gettin frustrated ! Thanks
