Could you provide a screenshot illustrating the issue? If you could also provide the raw text representing the checklist and any other content which illustrates the problem that would be great.
Which version of iOS are you using?
Thanks. I've managed to reproduce the issue - seems to be a problem only when a custom theme has been selected for export. I'll work on a fix for this, likely won't be in the next update (hopefully released next week) but will try and get into the one after that.
