Report tag history data source does not expand - similar example used in Inductive University

hi All
I just added tag history data source and when data is selected on design tab in the report in the inductiveuniversity video the data source does expand to individual components (first screenshot) but in my designer it does not expand (second screenshot)
copied from inductive video. Has anybody had similar issue ? I am bit stuck on this one :frowning:

my designer below

Have you enabled history on any of your tags?

Check the tag definitions in the tag browser.

it was as simple as you mentioned i did change history tag provider some time ago which broke history capture without me noticing immediately. This forum is really great for getting help. Many thanks
