Strange. My MWE was almost identical to yours except mine used the awsmath
package, because I'm working with an author who uses the align and align*
environments heavily.

When I strip out \usepackage{awsmath}, the equation renders as one image.
When using amsmath, only the part in parentheses is converted to an image.

Thanks for your help. The amsmath package must be the problem here.
