Help! Ring Transformer wont turn off landscaping lights

Hello, Under Lights, I have a group called Landscape lights. Under that group, I have my Transformer device. My transformer has a light schedule on for all seven days to turn the landscaping lights on at dusk and turn off at dawn. I even tried the custom timings but that still doesn't work. My issue is that the transformer turns the light on at dusk but won't turn off at dawn. I called Ring support and they told me to remove the group and create a new group and try again but that has not helped. I am really frustrated now as sometimes I forget to turn it off manually and some of the landscaping bulbs have already been dead. Any help would be appreciated.
