UC-UC Transfer -- Units and Class Standing??

So, I’m filling out the UC transfer application for Fall 2019 and I’m confused by the question: “How many college/university units do you plan to complete before you enroll at UC?” I answered with “90 semester/135 quarter units or more (senior transfer)”, but it restricted my ability to apply to certain UCs and majors.

I’m technically a 2nd-year student at UCSB, about to enter my 2nd year. But my class level is considered a junior because of the number of units I’ve amounted through my AP courses during high school (52.5 quarter units). Therefore, should I apply as a junior transfer or a senior transfer? Does AP units count in the “college/university units”?

Thanks!

From the UC Website:
Limitations on Transfer Credits

Students will be granted up to 70 sem/105 qtr units of credit for lower division coursework completed at any institution or any combination of institutions. For units beyond the maximum, subject credit for appropriate coursework taken in excess of this unit limitation will be granted and may be used to satisfy requirements.

Units earned through AP, IB, and/or A-Level examinations are not included in the limitation and do not put applicants at risk of being denied admission.
Units earned at any UC campus (extension, summer, cross/concurrent and regular academic year enrollment) are not included in the limitation but are added to the maximum transfer credit allowed and may put applicants at risk of being denied admission due to excessive units.
