I'm use walletrbf=1 in config for my Bitcoin Core v. 0.14.1 client.

When I try to send transaction with "bitcoin-cli sendfrom" the flag bip125-replaceable (Replace By Fee) is setting to "yes" correctly.
But if I try to make transaction with 
"bitcoin-cli createrawtransaction"
"bitcoin-cli signrawtransaction"
Replace By Fee is not setting (bip125-replaceable=no).

What should I do for making transaction with Replace By Fee by createrawtransaction?
Or this is a Bitcoin Core bug?
