upgrade to WP 5.2.2

Hello guys
We have site based on tribe events, it needs to be upgraded to last PHP, MySQL, WP and plugins versions.

We use plugins : The Events Calendar, The Events Calendar PRO,
The Events Calendar Shortcode & Block, The Events Calendar: Filter Bar, Event Tickets, Event Tickets Plus, Woocommerce.

After upgraded all is ok. besides main site page))

http://prntscr.com/o480h9 – this is current view of Event Archive page.
http://prntscr.com/o482nc – this is the same page on no-upgraded production site.
So, upgraded version does not catches theme-overwritten Tribe Templates.

The question – what is it and how to fix it?)
