There is an annoying bug with the latest version of Kendo UI for jQuery (2020.2.617). In grids with commands, there is a problem in column menu. When we try to show/hide a column, another column is hidden. Here is a sample that reproduces the problem : https://dojo.telerik.com/@kakone/awUhelIZ
. In this sample, try to hide the "Ship Country" column, you will see the problem.
