Does Dynamic Search work (SC8.1.030)?

In SC 8.1.030 I’ve just added a dynamic search to a grid.

When the grid is run and I click on Dynamic Search and then ‘add fields’, the dropdown will show the correct fields (the ones set in the grid Dynamic search settings).

But clicking on any of the fields nothing happens.

Am I the only one with this issue?

Never mind. After adding Advanced Search to the same grid, Dynamic Search started to work.
It also continued to work after removing Advanced search.
Sometimes SC is a mystery…
