Module Appears in the NgModule.imports of AppModule, but could not be resolved to an NgModule class.

I've added the the package as documented. When I add the module to my module's import, I get the following error.
node_modules/@asymmetrik/ngx-leaflet-markercluster/dist/leaflet-markercluster/leaflet-markercluster.module.d.ts:2:22 - error NG6002: Appears in the NgModule.imports of AppModule, but could not be resolved to an NgModule class.
This likely means that the library (@asymmetrik/ngx-leaflet-markercluster) which declares LeafletMarkerClusterModule has not been processed correctly by ngcc, or is not compatible with Angular Ivy. Check if a newer version of the library is available, and update if so. Also consider checking with the library's authors to see if the library is expected to be compatible with Ivy.
2 export declare class LeafletMarkerClusterModule {
Here's the output of my ng v

You may want to try the newer versions of the library that are ng9 and ng10 compatible. This issue was introduced when they upgraded to ng9 if libraries were not published with ivy disabled.
