Camera control iris issues with some lenses

HI,
I am in a live production with ATEM Constellation and 4 URSA Broadcast equipped with 2 Canon HJ24ex7.5B IASE lenses, 1 Fujinon Digipower 99 HD lens and 1 Canon UHD Digisuper 90 lens.
The Canon HJ24 lenses respond well to aperture control, while the 90 and 99 lenses do not, the aperture control is very slow and always in non-linear aperture shots.
Do you have suggestions?
Thank you.
