Airtag showed in different locations

One of my Airtags appears in three very different locations depending if I use "Find My" on my iPhone, Macbook or on my Macbook Pro. What is concerning is my iPhone shows the oldest location and will not update despite restarting, turning off and on Location Services, deleting and reinstalling the App. My other two Airtags are seen on all my devices where they are actually located. Anyone has had the same issue and was able to solve it? I guess my question is "how to refresh the location of an Airtag?" Thanks
