Tool tips and class toggle (change background) no longer works after conversion to BS5

I have input fields which I added tool tips to display the full value for the field in case the display of the value gets cut off. That no longer works when I converted to BS5. The tool tips I had for buttons works fine though.

Also, I had been using a class toggle to change the background for a form group based on the value within the form input field. That does not work also after the BS5 conversion.
