OK, what we have is:

"(?c)^(.*SMOKEYBEAR)$" does not match "smokeybear"

and at the same time:

"(?i)^(.*SMOKEYBEAR)$" does match "smokeybear"

How the latter is possible ?

I suggest you explain in your own words what those two regular expressions are attempting to do.  Why do you expect the second one to not match?  Why does the first one not match?
