Materials using anisotropy appears black in splitscreen

This occurs in 5.1 up to ue 5.4, during splitscreen play some materials appear black on one player screen. these materials are using anisotropy. when i disable anisotropy, the materials appear normal.
BEFORE (anisotropy enabled):

AFTER (Anisotropy Disabled):

Is there a better way to fix this? i have too many anisotropic materials
