Dependent visa category incorrect in visa appointment

Hi all,
I am scheduling an L1 Blanket visa appointment at Chennai. While adding the dependent profiles to my application, on visa options page of the dependents, my L1 blanket details were automatically copied to dependent profiles and there was no option to change them to L2.

I called the call center they informed me that dependent visa category is showing as L1-Blanket because of a system glitch and this should not be a problem as long as DS-160 has L2 for dependents. They asked me to send an email so that they can confirm it in writing. Waiting for the reply currently.

Have anyone experienced this issue and successfully completed the OFC (ours at Hyderabad) and visa appointment, though interview schedule is showing dependents visa category L-1 Blanket?
