We use W3C standards to test themes and have envato moderated the code before being sold on themeforest.
The tool you test is a tool with a completely different set of standards than ours, so it has as many errors as you can see.
To fix all the problems like the tool you mentioned takes a lot of time and has to change the code quite a lot.
Example <i> => <em> . icon tags
