Are you saying that you are trying to bridge packets at layer 2 with one
of the interfaces being in managed mode and not using WDS? If yes, that
is not going to work. IEEE 802.11 does not allow the station in Managed
mode to send packets with source address that differs from its own
address. You would need to either use WDS links (different packet header
with an additional address field for the original source address) or
simulate multiple virtual stations (i.e., multiple different addresses
that associate with the RemoteAP).

Host AP driver should able to do the first alternative (both in Master
and Managed mode). However, this may have interoperability issues with
other implementations if they require some kind of proprietary
registration. The other option would require firmware (or maybe even
hardware) change.
