So for starters, you can't use someone else's stash tabs. If you interact with the stash, it goes into your own stash tab. Unless you're referring to a guild stash, which is not your friend's stash.

As for the lost currency, assuming not in your own stash, then you need to check all of your tab affinities. If you set a different tab to currency affinity, then the currency will be in there instead. Which is why manually placing the currency works.
