The above image shows that i gave the field security so thats its visible to only particular groups, but when i accessed the interface from being in that group, i was unable to see the field even though i assigned the security so that it was visible to that particular group.

If you applied field-level security in the record type, I suggest to use the a!doesUserHaveAccess() function.

Sounds like OP is saying not even the field shows up (though i guess there's a chance we have a mix-up in terminology in play here as well). But if that's true at face-value, then AFAIK field-level security would not be impacting anything (yet).
