ROS 6.10 break specific route with routing-mark

hi there,

i am using CRS with ROS 6.9 and just upgraded into 6.10.
and suddently we found the spesific route with routing-mark does not work.
the counter at /ip mangle still work, but all the route with routing-mark are changes into blue colour at winbox.

back to 6.9 works normal.

anyone has the same problem ?
