Landscape: Terrain Height Map Problems

Hello All,

I am new to Landscape creation Process inside UE4.
I am importing a Height Map made in Gaea into UE4 but the end results look really horrible.

I am getting these Striations all over my landscape. Its not smoothed out. (See Images Below)

See below my Import Options. Not sure what I am doing wrong!!!
Any Assistance would be very welcome.

Kind Regards,
Chetan Biswas

Need to see if it have a good quality and in texture properties see the quality settings:
