ok another AI+ mercenary question

[seleucid empire]

I looked around every stack on the map using my spy and move_character

Getai: 1 unit of Mercenary Northern Gallic swordsmen. 1 unit of mercenary germanic heavy infantry (I think they only come as mercs?"

Bactria: 1 unit of mercenary pikemen 1 unit of merc persian archers (the ones with the green skin)

carthage: 1 unit mercenary pikemen, 1 unit rhaetic axemen, 1 unit ligurian infantry, one unit iphrakites reformed hoplites, 1 unit mercenary greek theuophi

Rome: none at all. instead they have fullstacks of triarii, celtic levy spearmen and illyrias. not a single mercenary. ( I was wondering is this normal roman behaviour on H campaign?"

Lustanion: none at all

Casse: none at all

So based on the above, is it possible i may have clicked Medium campaign difficulty instead of hard?"
also im playing on realistic movement mod and most factions have been wiped out It is only 240 BC does that also affect AI merc recruitment? Tbh I don't really care how many mercenaries they recruit I just want to make sure I am playing on hard difficulty because im kinda obssessive about playing only on H or VH
