Files being written to server root /tmp/ directory instead of site-specific one

The plugin is writing php files to the server root temp directory:

/tmp/wprss/twig-cache/c6

instead of to the site-specific temp directory:

/home/sejconf/tmp/wprss/twig-cache/c6

Did not find any options under Settings, support posts here or articles in the Plugin Knowledgebase on how to fix this so the temp files properly write to the /home/sejconf/tmp/ directory.

This plugin is the *only* one using the server root tmp directory. WordPress core and all other plugins are correctly using the /home/sejconf/tmp/ directory.

Any guidance on how to resolve this? Have copied the initial text (below) from one of the php files that’s being written if that helps to track down what’s going on.

Thank you.
