Search not working as expected due to MSO html code
I'm using RH2015, Build 12.0.4.460 to generate WebHelp. I have had reports of users not being able to find content that I know exists in the help. I have determined that the issue is being caused by what appears to me to be randomly inserted Microsoft Office (MSO) code. In the most recent example, a user did a search for "Processing payments before scheduled date". The html code reveals some random html code separating the "P" from the rest of the word "Processing".

This code is causing the search to fail. A search for "rocessing payments before scheduled date" works. We are not using the Tahoma font family, and we are using a Master page that, among other things, applies the .css page we want to use for styling the help output.
I have also noticed numerous replications of the following code block in the HTML:

If the above image is too small to read, the blocks are "CustomDocumentProperties" blocks. I did not intentionally insert any of them. If I delete them, RH seems to re-insert them.
Questions:
1) Is anyone else experiencing this?
2) Is there a way to remove all this MSO code?
3) Is there a way to keep it from coming back?
Note: If I do any block copying of text from MS Word into RH, I copy the MS Word text into Notepad, which strips out everything but the text, and then paste the text into RH, reformatting it in RH as necessary.
4) Is there a way to make RH ignore the html code and just look at the displayed text when performing a search?
Thanks!
