[lmt-post-modified-info] date not updating

Hello,
I am using manual shortcode, [lmt-post-modified-info] with ultimate members.
I want to display the last time the user has updated their profile and I’ve added the shortcake into the users profile.
Even when the user modifies their profile, the “last updated on (date)” doesn’t change.
Can you please inform me why the last updated date is not reflecting when using the [lmt-post-modified-info] shortcode?
Thank you!
-Richard
