Reflection tokens like Safemoon doesn’t show the reflections.
Also, if there is a tax when transferring the token like how SM has a 10% tax the automatic system doesn’t show this. Transfers in this isn’t really a problem. But transferring out this is a problem since koinly will think you have more coins than you actually have.
And since you can’t edit a transaction that is synced (at least the fee or amount that went out). You have to manually go in for each sell.
