"Copy as X" Features don't work in Sketch 62
Wanted to use the following commands:

Development |  
-- | --
Copy as PNG, PNG @2x, SVG | Copy seleceted layer as png, 2x png, svg.
Copy SVG Path Data | Copy SVG path data code from a selected shape layer.
Copy Slice as SVG Code | Copy SVG Code from selected slice layer.

but couldn't get them to work. Any requirements that the selected layer must meet to get this working?
Never tried it in other versions of Sketch before, but in v62 it seems to be broken.

Any help appreciated!
