We see Cheetara really flirt during the second season with Tygra and he flirts back with her.

That wipes all the presumed flirty signals in the first season out, which means she wasn't putting the moves on Lion-O in the first place.

Now as to her behavior in the first season. If she already had Tygra chosen, to her Lion-O was a future family member. So she would lay the ground work for a family relationship with Lion-O.
