Why do some Sonic Fronties LS look different?

Can someone please explain to me why some pictures of LS1 and 2's appear to have LED display's on them, yet some here on Agon for sale appear to have dip switches and no LED display. Have I lost it or am I missing something?

Sonic Frontiers first introduced the "SFL" series and then followed with "Line" series.
Unsound: Thank you.
