There are 3 states to the date stamp button in the e-sign menu of the viewer client. Clicking once enables the single use date stamp. Clicking twice enables a multi stamp functionality. Click 3 times and the user is returned to the single stamp functionality. There appears to be no way to "deselect".
Steps: Open full viewer > click on "e-sign" (top left) > click on the date button (farthest right in series) > click a second time on the date button > click a third time on the date button > hold the cursor over document white space
Expected Result: After clicking on the date button once, the button appearance should have changed (this signifies the single date functionality is active). After the second click on the date button the multi stamp feature should be enabled. After clicking on the date button a third time there are no more modes of functionality available so the state of the button should be returned to deselected state.
Actual Result: the 3rd click returns the button and functionality to the single stamp functionality state.
