No tracers on some Russian cannons?

Hi,


It appears that ShVAK cannons when equipped on I-16 and MIG 3 have no tracers.
LAGG-3 also, if only AP ammo is loaded. Viceversa tracers are present on the LAGG if HE or mixed ammo is loaded.
Bad luck for me, since my gunnery is so bad, nevertheless this opens interesting possibilities in multiplayer for those who can shoot.Can someone confirm?



Please help.

I didn't find the right solution from the Internet.
