CorelDRAW X5 :: Editing Of Custom Palettes

I am trying to edit a custom palette externally and have successfully done it in the past but now Draw is "breaking" my new palette.

I created a new palette within Corel Draw and added a single color. This is to create the XML file and generate a unique GUID. I can open and the close this palette with no issues. I can add colors via Draw with no issues. I then close Draw. I then open the file with a text editor (NotePad) and add the code for my new colors (pulled from a spread sheet). My code matches the code in the Draw-generated palette color. It also matches the code from another palette I successfully created over a year ago. The file saves just fine and can be reopened in the text editor. I then reopen Draw but my palette name is no longer in the palette list. Then if I manually try and add the palette by opening it, it opens but strips all colors. Then if I open the XML file with the text editor, the GUID is now all zeros and all colors have been stripped from the file. I have tried rebuilding the workspace and rebooting the PC but neither option seems to work.

PS here is a sample line of code for one of the colors I am trying to add.

"<color
cs="RGB" name="RLM00 Wasserhell"
tints="0.980392156862745,0.968627450980392,0.945098039215686"/>"
