if I use column chooser to first remove a column then click ok. the column is removed and then I can use the chooser again to add the column I just removed plus another column.

the issue only occurs after a grid import and then using column chooser to add a column.

To replicate this bug you need to successfully import a grid configuration using jqGridImport method.

Then activate the column chooser and modify the column list. in my use case adding a column to be shown.

click 'ok' and the grid body where you would normally see the data results is replaced with solid thick blue lines.

note: the column chooser works successfully before importing a grid configuration.
