multiple thumbnails/videos show only as last entry when displayed in a colorbox

Problem/Motivation

Drupal version: 9.5.11
Platform: Open Social v. social 11.11.4

When I enable Blazy Embed Field with the following settings:
With Use oEmbed when applicable with a VEF fallback toggled 1)* on or 2)** off (see below)
Loading priority: auto
Aspect ratio: fluid
Media switcher: Image to Colorbox

Video Field = Video Embed with YouTube, YouTube Playlist, and Vimeo enabled!

Videos combination of Vimeo and YouTube
Warning: Undefined property: stdClass::$thumbnail_url in Drupal\video_embed_field\Plugin\video_embed_field\Provider\Vimeo->getRemoteThumbnailUrl() (line 45 of modules/contrib/video_embed_field/src/Plugin/video_embed_field/Provider/Vimeo.php).

Thumbnails proper number of videos but repeat last video in the list instead of each individual video

Colorbox shows proper video count
With 1)* on = Website URL refuses to connect

With 2)** off = All videos display as last in list instead of distinct videos

But when I select Colorbox Model instead of Blazy Video Embed Field, the Thumbnails as well as Videos appear properly EXCEPT there is no navigation as there is with the above configuration.

Similar results happened with Blazy Video Embed Field v. 8.x-2.3

Any ideas appreciated!
