I got less on my amendment the it said I was going to get. What could cause this? I got 500 less

If the IRS sends less than expected then they also send a letter of explanation in the next couple of weeks ... so while you wait review the 1040X carefully ... is it correct ? 

Look at the form 1040X …

Column A should have the figures from the original return, Column C the corrected figures and Column B the differences between the other 2 which needs an explanation on page 2 of the form 1040X.

If you completed it correctly you will see an entry on either line 16 OR 18:

On line 16 should be the amount you paid with your original return. 

On line 18 should be the amount of your original refund you received.

Then you will see your extra refund on line 22 OR  the new balance due you need to pay on line 20.

It seams like everything is right from what you say. It hows up on line 18 and line 22 of the amount. Would them be my explication of the change was not good?
