Issues with Desktop Command on few features

There is an issue which annoys me every now and then is, in my project when I run the test live the steps do not work as recorded. The feature is a normal button which i tried walking over using the option of Desktop Cmmand(left click) and the Normal Click each. But the results indicate a test failure.
Find the logs using
a) Desktop Command
b) Normal Click
respectively
