Unable to locate elements through Appium inspector

In iOS we are unable to inspect elements, whenever we try to select a element the complete page gets highlighted. We checked in the source code and found that sometimes there also we are unable to find the particular elements. Even if we are able to find the elements through Appium inspector, and we run the automation scripts on that particular page we get element is not present on the page even if the element is visible.
Can someone suggest what is the issue and how to resolve this so, the team can proceed with automation.
