Preventing tags associated with journal block from tagging entire journal page?

Suppose I tag a block in the daily journal for September 23 with, for example, “X.” If I click on the “X” backlink, I will see that the page September 23 is tagged with “X.” This may not be desirable behavior, however, since many journal dates may have an “X” tag and therefore blow up the “pages tagged with ‘X’” field. Is there a way to prevent tags associated with a journal block from spilling over to the entire journal page?

Nevermind, I think I answered my own question. I was assigning tags as a property in the frontmatter. Doing so applies the tag to the entire page.
