BooleanColumn concatenate/doubles true/false-Labels and Default Labels in export

[tholag]

Prerequisites

• [x] I have searched for similar issues in both open and closed tickets and cannot find a duplicate.
• [x] The issue still exists against the latest master branch of yii2-grid.
• [x] This is not an usage question. I confirm having gone through and read the documentation and demos.
• [x] This is not a general programming / coding question. (Those should be directed to the webtips Q & A forum).
• [x] I have attempted to find the simplest possible steps to reproduce the issue.
• [ ] I have included a failing test as a pull request (Optional).

Steps to reproduce the issue

[ 'class' => 'kartik\grid\BooleanColumn', 'attribute' => 'ATTRIBUTENAME', 'trueLabel' => 'Yes', 'falseLabel' => 'No', ],

Expected behavior and actual behavior

When I follow those steps, Excel-Export will concatenate the Labels and the default labels to: "YesActive" "NoInactive" I was expecting Fieldvalues "Yes", "No" in Excel.

If I remove the trueLabel/falseLabel it concenates the default labels and exports the default label twice: "InactiveInactive" "ActiveActive"

This happens in all export file formats except html. App language is set to "de_DE".

Environment: PHP 7.2.42 Yii 2.0.43 kartik-v/yii2-grid dev-master 1aa635f (Same issue with v3.3.5)

Should not happen - update to latest release and ensure you have not overridden trueIcon and falseIcon - if error persists it maybe an issue with your configuration of the column. Do share the code to reproduce.
