Is this a bug in Turbotax where federal return is included twice when I want to print only California state return?

I am allowed to e-file my Federal MFJ return. But since my California state filing status will be different - MFS, then I have to paper mail my California return to FTB. If I understand the screen below correctly, it asks me if I also want to print my federal return for IRS. As can be seen If I pick "Do not print my federal return..."

And when I navigate to this screen that actually allows me to print state return:

I observe that generated PDF file contains:

1. Federal 1040 forms (but without Federal filing instructions page)

2. California filing instructions page

3. California 540NR forms

4. Second copy of Federal 1040 forms and schedules

Am I doing something wrong? Or is this

1. a bug in TurboTax where "Do not print my Federal return" option only removed instructions page, but still left copy of 1040 forms intended for IRS? OR

2. do I really need to send two copies of 1040 forms to FTB?
