Issue Summary

When using Content Manager in a space confirmed to have pages with no activity for over 6 months, applying Last Active: Over 6 months ago unexpectedly returns "Nothing matches what you're looking for". However, when the Last Active: Over 3 months ago filter is applied instead, the returned results include pages with values ranging from "7 months ago" to "11 months ago".

Steps to Reproduce

1. On a Confluence site, navigate to a space's Content Manager that have pages with a confirmed value ranging from "7 months ago" to "11 months ago" for the Last Active column.
2. On the Last Active filter, apply Last Active: Over 3 months ago. Observe that pages with a Last Active value ranging from "7 months ago" to "11 months ago" are included in the results.
3. Next, change the Last Active filter to Last Active: Over 6 months ago. Observe that the message "Nothing matches what you're looking for" is returned, even though there are pages with a confirmed Last Active column value of older than 6 months from the previous step.

Expected Results

The Last Active: Over 6 months ago filter should return pages with a confirmed Last Active column value of older than 6 months.

Actual Results

The Last Active: Over 6 months ago filter returns "Nothing matches what you're looking for".

Workaround

Use the other Last Active filter options (or no filter) to display pages with a Last Active column value ranging from 7 months to 11 months.
