Not working on PS4

[TPetersonWayforward]

Good day yall,

I'm having a bit of an issue with PS4 builds, unfortunately all the shaders in this package are failing in a ps4 build. I see lots of errors and warnings around 750 warnings and 8 errors regarding the shaders in the package.

All pretty much the same things, 2 errors for each shader, for example:

-------
Shader error in 'Hidden/UITransition': Program 'frag', ambiguous call to 'lerp'. Found 91 possible candidates: at /Projects/Game/PS4/Packages/com.coffee.ui-effect/Resources/UIEffect.cginc(263) (on ps4)

Compiling Fragment program with DISSOLVE
Platform defines: UNITY_ENABLE_REFLECTION_BUFFERS UNITY_USE_DITHER_MASK_FOR_ALPHABLENDED_SHADOWS UNITY_PBS_USE_BRDF1 UNITY_SPECCUBE_BOX_PROJECTION UNITY_SPECCUBE_BLENDING UNITY_ENABLE_DETAIL_NORMALMAP UNITY_LIGHT_PROBE_PROXY_VOLUME UNITY_LIGHTMAP_FULL_HDR
------

and this one:

------
Shader error in 'Hidden/UITransition': Program 'vert', ambiguous call to 'lerp'. Found 91 possible candidates: at /Projects/Game/PS4/Packages/com.coffee.ui-effect/Resources/UIEffect.cginc(263) (on ps4)

Compiling Vertex program with UNITY_UI_ALPHACLIP CUTOFF
Platform defines: UNITY_ENABLE_REFLECTION_BUFFERS UNITY_USE_DITHER_MASK_FOR_ALPHABLENDED_SHADOWS UNITY_PBS_USE_BRDF1 UNITY_SPECCUBE_BOX_PROJECTION UNITY_SPECCUBE_BLENDING UNITY_ENABLE_DETAIL_NORMALMAP UNITY_LIGHT_PROBE_PROXY_VOLUME UNITY_LIGHTMAP_FULL_HDR
------

and then tons of warnings all saying stuff along the lines of:

------
Shader warning in 'Hidden/UITransition': Program 'frag', or      : lerp(column_major float2x4 a, row_major float2x4 b, float d) (on ps4)

Compiling Fragment program with UNITY_UI_ALPHACLIP
Platform defines: UNITY_ENABLE_REFLECTION_BUFFERS UNITY_USE_DITHER_MASK_FOR_ALPHABLENDED_SHADOWS UNITY_PBS_USE_BRDF1 UNITY_SPECCUBE_BOX_PROJECTION UNITY_SPECCUBE_BLENDING UNITY_ENABLE_DETAIL_NORMALMAP UNITY_LIGHT_PROBE_PROXY_VOLUME UNITY_LIGHTMAP_FULL_HDR
------

I'm using this package in a few places, and I'd hate to have to give it up in the game I'm making, but I need PS4 builds to work. Please let me know if these can be addressed.
