<p>I can't reproduce your issue on my end, but I can offer an alternative method. Another way to create the circle example you've provided is to use a <em>Radial Wipe effect</em> on the shape layer:</p>

<pre><code>Effect &gt; Transition &gt; Radial Wipe
</code></pre>

<p>Just animate transition completion from 0 to 100 percent. If your shape layer is moving, you may also need to pickwhip expression the <em>Wipe Center</em> parameter to your position parameter:</p>

<pre><code>transform.position
</code></pre>

<p>I hope this helps you out. Good luck!</p>

<p>I have an animated circle shape layer with trim paths applied to it and the end percent animated from 0% to 100%. But half way through the animation, the circle path seems to close itself. How can i fix this?</p>

I assume your mask path is a full circle, try to use an outline as mentioned in the answer above.

I have an animated circle shape layer with trim paths applied to it and the end percent animated from 0% to 100%. But half way through the animation, the circle path seems to close itself. How can i fix this?

I can't reproduce your issue on my end, but I can offer an alternative method. Another way to create the circle example you've provided is to use a Radial Wipe effect on the shape layer:
Effect > Transition > Radial Wipe

Just animate transition completion from 0 to 100 percent. If your shape layer is moving, you may also need to pickwhip expression the Wipe Center parameter to your position parameter:
transform.position

I hope this helps you out. Good luck!
