It looks like the double well interests have different DOI. Perhaps the operator revised and resubmitted the deck decimals and as a result, your interest is now listed twice. Look at your check and DO to see which DOI is correct (and if it has changed). Then ask about submitting a copy of the recent check with correct DOI to have one or the other double listing deleted. Also, look carefully at XTO check because it likely has the 2 columns, one for royalty decimal and a second for distribution decimal. So that may be root of problem.
