I can't find any option to select any offer in Gig Packages.

Hello Dude,
I started working on Fiverr as a new seller. Sampriti I tried to open a gig in the Brand Style Guide category, but after going to the Gig Scope & Pricing option I can't find any option to select any offer in BASIC, STANDARD, PREMIUM for Gig's Packages. Now that I don't understand what I should do as a newbie, can you tell me if I can easily open the gig in the Brand Style Guide category? And how can I select offers in BASIC, STANDARD, and PREMIUM for Gig's Packages?
(Note: - I have added a screenshot so that you can understand and help me)

I look forward to hearing from you, thank you.
Have a nice day
