The error message you received could mean that you've selected the incorrect account for your expense transaction. Hence, the system asked you to select different type of account.
To resolve the issue, ensure to choose the correct account. For instance, if you're writing a check, choose an expense account; if you're writing a bill, choose either expense or accounts payable, and so on.
For the proper account to use, I recommend consulting your accountant to ensure your books are accurate.
