Failing to LINK layered PSD

Designer is up to date.

13.1.1 build 7509.

PC.

Expected result - A linked PSD should provide usable layers as resources.

Actual result - it displays the layers with warnings rendering them unusable.

• The psd file has simple layers.
• All use transparency.
• No folders,
• No layer effects,
• Just 8 painted layers.
• Link it into Designer, it sees the layers, you can tick them.
• But on loading every layer displays a warning and cannot be used in the graph.
• The warning suggests its trying to find a .png thats obviously not there or hasn't been converted to.

NOTE it DOES work if you IMPORT.

Just not if you want to LINK.
