Unable to Load ASE Swatch File as Separate Palette in InDesign

Oops… I meant to type “ase” file, but I can’t edit the title apparently. 

Hi all! I’m trying to load a specific swatch palette (not the default one). I’ve done it a million times. I’m running Indesign v. 21.3 on my Mac. I’m not trying to add it to the default color palette… I want it to be a separate palette. 

Today it’s trying to add a swatch to the library… instead of letting me open my .ase file. I’ve not encountered this before. I have nothing selected. 

What am I doing wrong? Thank you!
