Double Error but single highlightation

Example:
seh is good.

( sentence starts with lowercase)
( spell error)

But the spell error is only captured.

How to solve this inconsistency??

LT only shows one of the errors when two or more overlap.
in many cases the one shown is the core error, while the unreported one(s) are a side-effect of the first.
in many of the other cases the actual core error is still identifiable.

showing all overlapping errors could make it harder to identify the core error, making it a lot of effort for little gain.

Thank you for ur explanation.
