Mine did that and apparently, it's quite common.
I repaired mine with some epoxy and a couple of cable ties. BEWARE…. if you glue it with the pin in place, you can glue the pin in the enganged position resulting in a Gravityfixed rather than dropper. Also, if your alignment is only slightly out, the pin won't release/engage properly.
Bond it with the pin out using something else as a locating peg then ream out the hole a little once the epoxy has gone off.
You'll need to send it back to the US if you want them to fix it. They, nor the new importer, wouldn't replace mine like for like.
