Hello,
Now if we enable the variation swatches option everything is ok, there is no problem with product editing. We have created test products and changed type of your variations http://prntscr.com/pcwx2u if you prefer the different type of variation swatches or want to change it back to select just edit the attribute and change type back.
Also, if you want to disable variation swatches for the grid don’t hide it using display:none http://prntscr.com/pcwuvp disable it using Theme Options > WooCommerce (Shop) -> Shop elements -> Variation swatches https://prnt.sc/pcwvpp
Regards
