Issue: Data logging is not showing the most recent. It is variable on how long the data is lagging. From what I saw it has been between 0 - 2 hrs behind. This has happened on query tags and plc tags.

Show the tag historian settings for some of the tags that are lagging. (Sounds like normal behavior for tags with Analog Deadband style.)

Could it be a store & forward issue?

How is your historian configured? The data could be unavailable due to store and forward. If that's the case, you can use a history splitter and add a Local historian so the data is available on the local HMIs in real time.
