STB files are not showing up in the Plot Style Table (Pen Assignments)

I have the correct filepath set, however it only picks up on the .ctb files.  How do I get it to look for .stb files as well.  It works in all of my other drawings, but not this one.  I am using Autocad 2018.

Hi @Anonymous  The drawing is setup to use .ctb files instead of .stb files.  You need to use the CONVERTPSTYLES command to be able to use .stb
