[unpopularopp]

>but not "le es"

First of all it's a verb with -ik ending so you can't write "es", the root lexical word is "esik".

Second you never use anything like "le es" because generaly you always have to use the verb and prefix together ("leesett", "leesik" etc.) unless you use a commanding form ("ess le") or a modal verb ("le akart esni, "le fog esni" etc.)

"le es" is strictly wrong because it's the wrong verb (should be "esik") and you have to write together ("leesik") so obviously a spellchecker picks that up.

[jiggawatts → unpopularopp]

Okay, I admit, my Hungarian is not so good these days.

But if you're right (seems like you are), then why do spell checkers not pick up on "es" as misspelled?

[unpopularopp → jiggawatts]

Most likely because it's used as a suffix too.

Mostly for numerals:

"I arrive with the train at 7" [as in 7 o'clock] = "A 7-es vonattal érkezem"

"M7 motorway" = "M7-es autópálya"

"50m² room" = "50m²-es szoba"

But it's also used with foreign names and full names.
