How did you export the save from your Wii U? SaveMii?
I had an original save file on the Switch before injecting the converted ones, maybe that helps.
Has anyone tried one of those Chinese knock offs that look exactly like a Wii U Pro controller but without the Wii U logo? I Have one but it's not...
Under releases you can find the Windows UI
I'm a new user so I can't provide the link to the software but it's on github called BOTW Save Manager by DeltaJordan.
It worked for me two days...
