Deleting Layer Slide Is Deceiving

I just upgraded to the 3.6.1 version of Meta Slider (and I also have the Pro add-on pack installed) and something weird happens when I delete a layer slide. The interface looks very different. Instead of the red trashcan icon, I now see an X to the left of the General tab, and when I hover my mouse over the X, the tooltip says Delete. Clicking on the X doesn’t seem to do anything, but when I refresh the page, I see that the slide actually did got deleted. In contrast, when I delete an image slide, the slide fades away almost right away. So it was just disconcerting that nothing seemed to happen when I clicked the X on the layer slide because the slide still remained visible.
