No, I only used Nusspli downloaded to USB to install on USBIt means you didn't downloads that title with NUSspli but from some obscure source which doesn't contain all files. Just redownload the title with NUSspli so it will download the title.tmd file directly from Nintendo.
On that HDD i have content installed with WiiU USB Helper + WUP Installer
Never from an unknown source.
Edit: thanks for the quick reply, btw
