If the file was dumped incorrectly from a physical cartridge or a digital eShop purchase, the compilation process may completely omit the program metadata. Bad conversions from XCI (cartridge format) to NSP can also strip the program type designation entirely, rendering the archive useless. Step-by-Step Fixes
The error is for playable titles. The "fixed" suffix in the error string is a software artifact, not an actual repair. Only reintroducing the original or bit-identical Program NCA resolves the error completely.
Download the latest sigpatches corresponding to your current Atmosphere and Hekate versions from a trusted homebrew repository.
If updating your sigpatches does not resolve the issue, the problem likely lies within the file itself. If a download drops even for a split second, the file structure can corrupt, leaving the Programtype NCA unreadable.
Method 2: Verifying and Repairing Corrupt Archive Extractions

Extract the contents directly to the root of your SD card. Overwrite any existing files if prompted.
