Zoom-n-Pane Function not working after HTML5 export

Problem: The Zoom-n-Pane function is not working in the HTML5 output which has been exported. Inside of Activepresenter the zoom-n-pane function is working. What could be the reason for that ?

ActivePresenter Version:8.0.6

OS: Windows 10

Notes: The HTML5 output has been tested in Microsoft Edge, Google Chrome and Firefox

Please make sure which modes you want the zoom-n-pan effect to be shown in HTML5 output are checked in the Show In Mode section. Maybe this caused the problem I think.
show in mode

indeed. On some slides the chosen mode was not checked in the properties.
Thank you very much for your fast reply !
