Unexpected behavior from Albums->Manage

[mr10points]

New install Pwigo 13.1.0, PHP 8.1 {bcmath,fpm,xml,mysql,zip,intl,ldap,gd,cli,bz2,curl,mbstring,pgsql,opcache,soap,cgi}, Mariadb 10.5.15

When you select "This is a SmartAlbum" from the Albums->Manage "SmartAlbum" tab, you do not get any options and it selects all photos.

When you access with the Plugins Menu and select SmartAlbums->Settings 'Create a new SmartAlbum" you get the two warnings below:

Warning: Undefined array key "filters" in /var/www/xxx.home.ca/_data/templates_c/p6jhns^5eb571b15d017e45c914fcaea3127b1e40edd927_0.file.album.tpl.php on line 386

Warning: Attempt to read property "value" on null in /var/www/xxx.home.ca/_data/templates_c/p6jhns^5eb571b15d017e45c914fcaea3127b1e40edd927_0.file.album.tpl.php on line 386

If you continue and use the "add a filter" dropdown, you can select a filter type, but cannot add the particulars of the filter

No apparent issues on old install with PHP7.4

I have the same problems (Piwigo 13.4.0, PHP 8.0)

IS this related to #18? @raupie put in a PR for it but I couldn't get it to work on my end. I am not well versed in PHP so I am really not sure whether I am implementing it properly. @HStep20 suggests that it doesn't work either.
