Changing group appointment to individual for US H1-B Visa renewal in Canada

[kpv220]

I am applying for a US H1-B Visa renewal. I filled all the details in my form and set a place for the Visa interview appointment. My "current status" was showing "Ready for Appointment". Then, I clicked the "Add Person" icon by mistake and now, there is a new section opened saying "Add Applicants" giving a new IVR number and my "Current Status" was also changed to "Add Applicants". I want an individual appointment and I clicked on the group icon solely by mistake. I tried searching many forums about this mistake and I could not find any answer about this. Is there any way to change this group appointment back to individual appointment? Will this be a problem? Is there anyone I can contact about this?

Please help.

Thank you!
