Hi, @ldk. Thanks for reaching out.
In order for expenses you've entered on bills to show on your Profit & Loss report, you'll need to make sure that there's an expense account associated with them, as shown below. If that's not the case, just hit the drop-down and choose the appropriate account for the transaction.
If there's an expense account associated with the line items, then your Company File may have data damage. To check for data damage, I recommend doing a Rebuild & Verify.
Keep me updated here and I'll ensure we get you back to business. Have a great weekend ahead!
