Agree, Its understandable if SR makes mistakes with hindi or some other language..Its funny this one, coz every major city or town for that matter in South India has atleast a significant population from all the other three states, be it AP,KA,KL or TN and languages are also so similar and spoken widely..
.
Anyway i dont think its a big deal, might be a unnoticed mistake by SR. Is there any way to let them know? Probably e-mail or please report in C&W office in RMM..
