I just realized the problem was I was not leaving a space between the NextGen Gallery tag and [singlepic id=1359 w=320 h=240 float=left] and the post. When it was like this [singlepic id=1359 w=320 h=240 float=left]Start it removed the S vs. being like this [singlepic id=1359 w=320 h=240 float=left] Start where the S would appear. Not a perfect solution but it works. Must be something about how the feed is stripping those tags in particular – just add a space and the problem is gone.
