Sitecore E-commerce FE: Issues with Custom Product Templates

Installed Sitecore E-commerce FE and example packages. New products appear in the search group, but altered product templates do not function; only sample templates appear valid. What is missing?

hey, did u chk if the custom temlate files are in right folder? sometimes the configs arent merged propely so it defaults to sample. try clearing cache and resetting path, might do the trick.
