Pella Screen Door Strike Kit

I am missing the part that holds the screen door latch can someone help identify the part

I just ordered the Pella Screen Door Strike Kit.(85-016) Will it replace the one in the pictures I have added?... I do not see the little plastic piece (in the kit)that is actually the piece that is broke? We have 2 screen doors and there is a picture with one that works...and then the other one ... (cont.)

Pella slider with cassette screen door. The plastic clip keeps the screen closed

I need to replace the broken clear piece which the retractable screen clips into

We have a three-section patio door, middle section is a slider and has a roll up screen. The small molded plastic piece in the strike plate has broken and we are trying to find a replacement.
