I am using LSBuilder 2.3.1.26192.
We have a series of readings on the Catechism that we use each week. I have spent many hours putting these as a "Write Your Own" custom element in Builder. Every so often, we will notice typos in the bulletin in these elements - the first letter left off of a word. This typically seems to be either the first word of a paragraph or the first word after an elipsis (...). When we go to correct the typo in the Edit My Worship Resources window, the custom element is correct. It is also correct on all the other pages (Plan Service, Edit Bulletin) and in the HTML export of the service. It seems to only happen when we save the service to .doc. (I also just tried it in .rtf and .docx. RTF omitted the letters, .docx was OK).
I am not sure why it would omit letters in the middle of a line, but it seems to be happening every so often.
