Larry, sorry for delay, I finally got a chance to look at this issue. First of all, the "STATUS" element for both of those units is wrong--for reinforcements entering by turn, it should always be "1". There should also be an "ENTRY" element with the relevant turn number (you might have to add or subtract one for the turn number, the XML is inconsistent in this regard). The STATUS codes that those units have refer to "Mobile" and "Fortified," so they should not appear as reinforcements.
Anyway, I could not replicate this...I exported the scenario to gam, opened it in Notepad++, changed the icon colors for a bunch of units (which were also reinforcements), saved the Notepad++ file, and reopened it TOAW IV, and all of the reinforcements had the appropriate (ie, non "1") numbers.
Not sure what might have happened...the only thing I could think of is if you did a search and replace during the color replacement, you might have inadvertently changed some of the STATUS codes, although that doesn't seem particularly likely. Let me know if you think I left out some step that might have changed the result, and I can try again.
