Niagara warning in builder

I have a Niagara system that keeps getting this builder warning.

LogInit: Display: LogNiagara: Warning: Could not cache cooked shader for script …GPUComputeScript because it had an invalid cached script id. This should be fixed by running the console command fx.PreventSystemRecompile with the owning system asset path as the argument and then resaving the assets.

I tried the fx.PreventSystemRecompile suggestion but no change. There is no indication of an issue in the system log. The only way to know is when it goes through the builder. Nothing too complicated in the system. Just one emitter with a Skeletal Mesh module

Any help is appreciated.
