Does not work Aspect Ratio Axis

I just switched my project from version 4.25 to version 4.26.
And found that the Aspect Ratio Axis is broken.

Our project uses the parameter for widescreen monitors:

[/Script/Engine.LocalPlayer]
AspectRatioAxisConstraint=AspectRatio_MaintainYFOV

I ask for help in solving the problem. This parameter is important.

I have same issue.

Please fix it epic guys!!
