We received the same error. It seems to be related to pages designed to work on mobile devices and selecting a button that would appear within a dropdown menu. To resolve, we reduced the window size of the WPM recorder and perform the recording that way. Reducing the window size of the WPM recorder made it display the page as it would on a mobile device.
Take a look at WHAT WE'RE WORKING ON FOR WPM (Updated Nov 13, 2019) , the upcoming version of WPM will let you define the resolution of browser window in which you want to create the recording. In WPM 3.0 sometimes the resolution in which the sequence was recorded may be different than resolution in which it is played back by the player and then if the recorded page change its structure due to responsive design it may lead to problems with locating elements which you experienced.
