Hi David, sorry to hear you're still having trouble with this! We recently learned of another LastPass setting that can affect these behaviors and I wanted to see if you can test with this turned on for me:
Recently LastPass stopped adhering to those by default and so turning that on should do the trick with any luck. We do have some fixes in and around these areas coming in a release soon though as well so definitely keep an eye out for that.
