Roommates didn't get permission to sublet to me, now adding me to lease... but my payslips show our current address?

I've been subletting for a month, and now my roommates want to add me to the lease. I need to submit payslips when doing this. However, I read through the lease and saw they needed written permission to have me sublet, so I asked them if they had done this and they said no. When I told them my payslips have our current address on them, they told me they can redact it before sending it over. I told them I am not comfortable with that, and if they want me to sign they would have to explain to the agent that they were subletting to me and now adding me.

Could I get in trouble for this? I'm on a visa and really worried about what could happen. They reassured me that they have a good relationship with the agent/landlord and it shouldn't be a problem, but the fact that the lease states rules against subletting multiple times is making me worry about breach of contract. The lease is only for another 2.5 months.
