dplvar values being lost in the middle of page template expansion.

[imyopop]

DynamicPageList3 version: 3.4.5
MediaWiki version: 1.37.1
PHP version:7.4.29

List of steps to reproduce (step by step, including full links if applicable):

• Set a value using dplvar - {{#dplvar:set|enhview|titleonly}}
• Check for that value in many templates - {{#dplvar:enhview}}

What happens?:
It is valued for a while, and then stops, and then comes back

What should have happened instead?:
The value should have always been there until it was erased.

If you click on the gold arrow in the purple circle, with the question mark, you can see

The template looks for that value, and puts just a title if it finds it. With extra data written to the screen I could see the value was there for everyone but the one with the large text pieces.

Not necessarily asking for you to figure it out, but is there a way for me to see when it changes, or if the template processing is not thread safe.

I have an update. The cases where this happens the template call is {{XXX}}, however, if I put an empty first parameter {{XXX|}} it doesn't happen.

I have fixed the real pages, but have created one in my user page:
