I'm guessing you were making edits and continually re-checking XTools. For performance reasons, there is a 10 minute cache on all queries in XTools, so what you see could be outdated by up to 10 minutes. There's a feature request to be able to purge the cache at T209334: Allow users to purge the cache. Another possibility is that the replica database was lagged which can also result in outdated counts, but if that were the case you should see a warning at the top of the page in XTools.

Additionally, note that XTools counts your edits differently than MediaWiki does. For more information, refer to the documentation: https://www.mediawiki.org/wiki/XTools/Edit_Counter#Edit_counts

Closing as invalid, assuming the issue was either cache or replication lag.
