Just wanted to follow up. We have figured out the issue and we are in the process of figuring out how to fix it. In the meantime, the workarounds are thus: Either open the text frame, which seems to make the fragments disappear, or use a paragraph text frame (tap-drag a text frame, rather than just tap with the text tool.) the problem appears to be specifically related to point text frames. Hope that helps. I'll let you know when a fix is in place.
