Our developers have identified the cause, and the official fix for the issue should be released in few weeks from now. I don't have anything more specific, though, I'm afraid.
I would like to inform you that we just published new version for the following Toolset plugins and that contains the fix for the issue "select all checkbox broken" on post type listing page.
Could you please update ALL Toolset plugins to it's latest officially released version. You can download the latest plugin release from your account's Downloads page:
