Additional activity types within my Garmin Connet App are not shown in my watch (Forerunner 235)

I have activated some additional activity types within my Garmin Connet App. Afterwards I dit a Synchronisation with my watch. (Forerunner 235) But I can't find the new acticity on my watch. The watch shows only the standard types runnin, cycling and others but e.g. walking is not shown. What is my mistake? Thank you, Frank
