Job title from previous employer doesnt match eta 9089

Hello

My employer filed perm for me however i realised there was a small issue

So i worked in three companies A,B,C
My current is A and B,C are previous

In eta 9089, it is mentioned that my title at C as network engineer however in employment verification letter providesd by c it is consulting engineer
This is because, after i left c , the company c has changed designation

Will this cause any problem to my perm?

Job title can be anything in the company and it usually varies from employer to employer.

As long as the job duties are same, you should not have any issue.
