[Gelöst] Issue with Grid loop in Elementor pro and filtering second language

Background of the issue:
I am experiencing an issue with the loop grid and filtering in Elementor Pro when using WPML. I found a topic related to this issue: https://wpml.org/errata/elementor-pro-taxonomy-filter-feature-not-working-for-secondary-language/. However, the code on line 691 in my PHP file is different from what is described in the topic.

Symptoms:
The filtering does not give the expected results

Questions:
Is my issue the same as the one described in the topic I found?
Can you help me fix the filtering to work in Dutch when the website is in Dutch?
