IE11 Google Toolbar no auto search suggestions, no search history?

Since the last Win 10 update my Google Toolbar won't list any search suggestions as I type and there is no search history listed. The Google tool bar will allow a search, but after a few searches no search history shows and no "clear search" button is listed either.

I have turnd on "Suggest searches as you type", and "store search histroy on my computer" in the Google Toolbar options.

Any suggestions to fix this?
