Shrinkwrap collision isn't wrapping everything

Development Rendering
1

As you can see I’m using a fairly simply shape that’s 704x128 pixels.

For some reason the shrinkwrap isn’t hitting all the crevices.

The image was 1408x256 but I resized it and re-imported. I’m having this problem with quite a few of the images I reimported. I clicked YES TO ALL to replace, and NO TO ALL to keep settings.

I also tried to delete this image entirely and reimport fresh but it still wraps the same way.

See photo.

I actually figured out the problem… unfortunately after posting. But I now have another related question.

To fix this I raised the Detail Amount under the Collision Geometry setting. I have 100 of these images to go through. Is there a way to quickly set the Detail Amount on all of them at once?
