Schedule D AMT

The tax software I am using produced a totally unnecessary schedule D AMT for some reason. It looks exactly the same with my normal schedule D and I have nothing to do with AMT (assume this statement is true). My tax return is really very simple.

Otherwise my tax return seems ok. Can I go ahead and efile with them? Or submitting an unnecessary schedule D AMT will create a problem and I should not use them and pay somewhere else again? I have no idea why it created schedule D AMT. First it didn't even create it. But now it is creating.
