Can't find auction length for new auction

I cannot find how to set the auction length. If I select 7 days in the create auction in the dashboard the auction shows as being 365 days. If I create an auction on the website there is no option and the auction is 365 days.
If I look at packages I don’t see an option for auction length
If I look for tpl_account I cannot find it
If I look at submission packages there is no option.
I’m probably just blind, but can someone help me out?
Thank you
Kevin
