I'm experimenting with showing cash in linked checking accounts rather than in brokerage accounts in QW2018. When converting to linked checking accounts, I periodically see the dialog below.
This transaction was created as a transfer to an investment transaction. If you edit the category, the corresponding transaction will be deleted. Do you want to change it anyway?

I don't know what it means.
- There is no indication what "this transaction" is.
- There is no indication what "edit the category" or "change it" mean in this context.
- There is no indication whether deleting the transaction is the right or wrong action to take here.
Can anyone decipher this for me?
