QueryXML output as text only outputting one result

Hello,

I believe this was working in 2007, but I'm just getting back to development on this workflow after an upgrade to 2010. I use the Call a Web Service action and use the GetList method and then XPath to query the results. The query works fine, in the Run Now > function I can see the exact return I need, and it looks like this:

Output 1
Change_x0020_Tolerance_x0020__x0
Change_x0020_Tolerance_x0020__x00

I have the Return result as: set to Text, and I've tried a Single line as well as a Multiple lines of text variables, but when I log the text variable to history directly after the Query XML action, I only get:

After that I use a Split Expression on the word 'Change' to create a collection (and the first step in the For Each after is to add the word 'Change' back so the field names are useful again).

What I used to get is for the query result is:

Any ideas what may have changed? I haven't done much with this workflow before the last few days. How can I restore the expected functionality? I've been searching but haven't found a related answer yet - sorry if this has already been covered.

Thanks!
