SharePoint and CAML query help

I have created a caml query that filters based on fiscal year (2016,2017,2 etc.).  The problem that I have is the results are wrong sometimes.
Below is my CAML query

 var prjQry = "<View>"+
	    			"<Query>"+
						"<Where>"+
							"<Or>"+
							  "<Eq>"+
							  	"<FieldRef Name='Design_x0020_Obligation_x0020_Da' />"+
							  		"<Value Type='Text'>"+vaFY+"</Value>"+
							  "</Eq>"+
							  "<Eq>"+
							  	"<FieldRef Name='Construction_x0020_Obligation_x0' />"+
							  		"<Value Type='Text'>"+vaFY+"</Value>"+
							  "</Eq>"+
							"</Or>"+
						"</Where>"+
		    			 "<OrderBy>"+
		    			 	"<FieldRef Name='Prioritization_x0020_Total' Ascending='True' />"+
		    			 "</OrderBy>"+
	    			 "</Query>"+
	    		"</View>";

Select all Open in new window

here's the result when filtered by '2017' which is correct:

here's the result when filtered by '2018' which is wrong.  I have no idea why data is being returned.

here's the result when filtered by '2020' which is correct:

Any idea why the inconsistent behavior?

Thanks!
