Hi, I am very new to Ignition and trying to figure out my first project. I have tags created by MQTT that appear under different directories based on a topic. I have selected a few to enable history but some get saved into DB and the others do not. I do not see any difference in the setup between the 2 groups other that being from different directories. The current values are displayed for all and have current timestamp. Any suggestions on how to resolve this?

PS. The 2 groups of tags were enabled at different time, do I have to refresh or restart anything to apply the change?
