In RH9, random conditional build tags appear within topic text

I have assigned conditional build tags to text within a topic. After closing the topic and re-entering at a later time, other (additional) text now has the conditional build tag assigned as well. However, I did not assign the tags to those other sections of text.

I do not have any trouble assigning a conditional build tag at the topic level. The issue only occurs when a tag has been assigned to text within a topic.
