Tier 1 PSW Dependent Visa question

Hi,

I just wanted to verify what is the meaning of these questions, this is from the online application form for a dependent of a Tier 1 PSW visa:

6.7 Have you ever been deported, removed or otherwise required
to leave any country, including the UK?
- on this question , it is clear to understand

6.8 Have you made an application to the Home Office to remain
in the UK in the last 10 years?
- but on this part, thus this question relate to 6.7 stated above. Cause from the form, there is another entry 6.4 stating almost the same question. please see below:
6.4 Have you been granted a visa for the UK in the last 10 years?

Can you please help clarify if the question on 6.8 is related to 6.7 or is it a separate question and you need to supply the Home Office Reference number which we couldn't find with the same format as the stated on question 6.8 and 6.7

Please help us clarify these concerns.

Kind Regards,

Sepay
