View all works by artist link runs with default filter settings

Example

https://en.numista.com/catalogue/artist.php?id=1369

Most of his works are in medals category

https://en.numista.com/catalogue/index.php?g=%22Werner%20Graul%22&ct=exonumia&p=1

Link looks like it will be searching medals and tokens, but when I click it I get search results with only coins enabled. Probably my default filter settings.

Yes, that's correct and I guess this is working exactly as it should. 

Simply remove the filters to see all works of the artist. Or, change your default settings.
