I just upgraded from 3.8.1 to 4.1.2. Everything seems to be working well except for the checkboxes in the left column (created automatically by multiselect = true). This is what I am seeing:

1. Select the Select All/Deselect All checkbox at the top of the column – only the first row is selected/unselected.

2. Nothing is selected, select the third row – the first and third row become selected.

Now select the fourth row – the first row becomes unselected and the fourth row is selected.

Now select the fifth row – the first row becomes selected again and the fifth row is selected.

3. Now select the Select All/Deselect All checkbox at the top of the column – only the first row is selected/unselected.

Am I missing a plugin or something else that would make this work? I do not have any functions such as beforeSelectRow, onSelectRow, etc.

Thank you in advance for your help.
