Truncated view of content in engagement drop downs

It appears that the truncated options in the dropdowns stem from the HTML generated by the Lifter admin pages. The value attributes are truncated, as well as the actual text that should appear in the <option>.

We’ve tried turning off most plugins – this made no difference. Our theme is a minor adaptation of Twenty Eleven, with no changes that might affect the admin area. We can’t work out why this might be happening. We are running Lifter 3.14.7 on WordPress 4.8.2.

Thank you for any help you can offer as we cannot automatically send out certificates at the moment and we are beta testing a course.
