We have reports about the Essential Grid problems with the WPML plugin. Would you please do a test:
Try to disable the WPML plugin temporarily and check the website in a normal mode and see if it works correctly. This will help to understand that if it is related to the site being multilingual or not.
I also will appreciate to give us screenshots of detailed settings that you have in Essential Grid.
Finally, please test the case with another bundled plugin about the grid called The Grid:
There is no problem reported regarding The Grid and multilingual websites so it can be a good starting point.
