After updating to version 19.1.1 CC 2018, the Select and Mask tool on both my Mac and PC is not working (no sliders in the properties panel). I eventually found a new tab 'Reset Select and Mask' in the spot where you normally change your workspace. This tab is unique as far as I can tell in that there is no equivalent for any other tool. Neither is this tab documented. Also I found nothing by Googling the issue with a broad range of search terms. Anybody else had the problem?
