This is really messing everything up. I haven’t been able to find a solution to this. We shouldn’t have to wait for Koinly to fix this. There should be a way to assign misinterpreted tickers to the correct coins ourselves.
The reason this is happening is because we don’t have most of the ASA assets currently imported in Koinly so they are assumed to be similarly/identical named tokens on other chains.
So unfortunately there’s no way to assign them to the correct one because it doesn’t exist in Koinly yet.
But we are working on this, so hopefully it won’t be much longer before this will all be sorted automatically
Sorry for the inconvenience!
As a workaround you can use any of the NULL1, NULL2, NULL3 etc. tokens as placeholder for the ASA if you need to urgently file your taxes.
