Libreoffice impress deletes slides

Hi all,

I have a problem with the recent release of Libreoffice Impress ( that came with an update. The slides are deleted when I click on the slide pane and I lose work because I do not even notice when it happens. It seems to be triggered by the combination of a mouse click and slight dragging. Another similar behaviour is that if I left click and pull the slide towards right, the slide is copy-pasted.

Does anybody know if there is a way to disable these functionalities?

Thank you.
