Whats worng?

Whats wrong with these Pokemon (to use them Online)... According to PKHex, these Pokemon have wrong attacks, but they can still be learned by TP. And a problem is that the ability is shown as wrong, but it should actually be that way

You have to put a checkmark next to the move you want the Pokemon to use on the Technical Records list on your Pokemon (under Relearn Moves).

GortromX - TR10

LiberloX - TR74

IntelleonX - TRs 05 and 33

GaunuxX - TRs 32 and 90

As for the abilities, Hidden Abilities are not available, meaning the 4 Pokemon you listed cannot obtain those Hidden abilities in-game.

Ok thanks... but why does they have the secret ability, whet it's unobtainable

[Matt (Wii Sports)]

Some Pokemon with hidden abilities can be obtained from events.

(ex. Hidden Ability Johto starters event lasted from Feb. 27 - Nov. 30, 2015)

Or, in this case with Sword and Shield, Max Raid Battle Events. Pokemon from Max Raid events have a chance of having a hidden ability.
