I think my Animation in unity is glitching

I have an animation in unity, the animation starts and goes normally, however in the last last millisecond before the animation transitions to the empty state, my animation is showing a millisecond of the beginning of the animation, so each time i play the animation, in the end i got a pop up almost pic of the how things are in the start of the animation clip, it is in fact barely noticeable, but if i can stop it, i would very much love to, is this just a glitch or is there a way i can stop this from happening ?

There’s “Exit time” parameter in mecanim. Set it to 1.0

It didn’t work, but i did try turning on Fixed Duration and then set the exit time to 0.75, and the transition time to 0.25 and now it works, thanks anyways
