RHEV Self Hosted Engine setting change but not refresh in manager GUI

I set up self hosted engine RHEV 3.5 and apply all packages to last version.

first, RHEV-M self hosted VM is 2 cores, 4096M Memory.

so i change vm.conf

memSize=6144
smp=4

and restart hosted-engine

it looks good.
/proc/cpuinfo,
free -m
hosted engine settings' nicely changed.

BUT!
RHEV-Manager WEB UI's values are not changed

is this bug?
