Any ideas on why the 'Run from here' functionality goes away?

While I’m troubleshooting a test, if the test fails on an error, I will correct the error in the test and use the ‘Run from here’ option to restart where the test failed. However, in some tests, the ‘Run from here’ option is greyed out and not selectable. This seems to happen at a specific point in the test. For example, in the early steps, I’m able to restart from a certain point, but as the test progresses into the later steps, I seem to lose the ability to ‘Run from here’. Anybody else experience this or know what causes it?
