When I import a video color changes drastically

Hi,

I record my screen using Camtasia and when I export the video the colors are perfect. I played video using 3 different players colours are intact.

But when I import the video to Final cut pro x the color changes drastically, all the settings are set to default and no color grading is added. I tried to make changes under settings as you see in the video link below and nothing is working, and here is the link www.youtube.com/watch?v=UQjsDZANDzw&ab_channel=UpliftR

Please help. Thanks in advance...
