Sorry the forum kept resaving the same post over and over and would not let me delete dupes.

All fixed now but it was a bit hard to figure out the correct security name in typeahead list - had to type "Treasury'

Fixed. I had to enter the precise security label by trial and error for this to update. Entering any other text or numerical value,  like the screenshot, causes the update to fail
