The form is quite clear, that if you are, or ever were, a student, then you need CSI. But... do you? And more importantly, did you, 15 years ago?
In answer to the question - no.
You only needed to have CSI during your time as a student if you want that time to count towards your PR qualifying period. If you have a continuous 5 year period of work (preferably which ended at least a year ago if you have dreams of applying for citizenship) then just use that. It doesn't matter which period you use.
I'm an EEA national living in the UK for 25 years, I never had CSI during my time as a student (3 years), however I have worked for 7 years since then, and I applied using the last 6 years of that (1 year buffer so I can apply straight for citizenship afterwards). It wasn't a problem.
For peace of mind, you can state in the "additional information" box on the form that you wish for a certain time frame to be used for your qualifying period (this is what I did). Or you could apply on an old form such as EEA3 which is much simpler and shorter. UKVI cannot reject applications made on old forms, in fact you can write a simple letter asking for a
document certifying permanent residence and as long as you provide sufficient information and the required evidence, they cannot refuse that either.
You should be aware that the actual date that UKVI determines you to have gained PR is not printed on the document that you will receive. You can find out the date from UKVI by doing a subject access request, or alternative if you use NCS when applying for citizenship, they can find out on the phone during the appointment.
