Hi, Max,
Thank you for the provided images.
In general, this might be caused by different JavaScript or Kendo UI library versions. Could you try to update the scripts and styles to the latest version for both grids?
With that aside, the exact positioning of the filter icons depends on the theme that is used. Could you let me know the theme that you are currently using? They are divided into two categories - LESS-based and SASS-based themes.
Furthermore, it would be great if you could provide your configuration file or a demo with the faulty behavior. Here is a dojo template with the latest versions included:
I will be glad to assist you further.
Kind Regards,
Anton Mironov
