Transfer toolbar buttons disappear when changing settings

In the Download or Upload tab, the Expand and Clear buttons disappear when I change a setting in the bottom bar.

When hovering the mouse there's a small button that does nothing.

I have to click in the transfer windows to get the three buttons back.

Not really important, but I thought I'd mention it.

I love the new client, btw!

Best wishes
