Do you think it is coming from the mouthpiece area or directly from the bottom?
I ask because I think some of the "leaks" are actually condensation or that tiny half drop of juice that gets caught in the area around the PTF opening.
In a fortunate kitchen accident, I found the sliding MP to be easily reattached and as needed, detached again. (I fill with a 100ml bottle)
Under the sliding MP, on the pod and within the MP hides a drop or so of AWOL juice.
When refilling, I remove the MP slide and dry any juice found on either the MP or the pod body/rubber gasket. (remember to ream out the MP "drip tip". )
You can also twist a corner of vaper towel into the air hole on the pod to dab up moisture.
