should we use banned instead of banning? what's incorrect in this sentence? [closed]

In 1971, US government not only put warnings on cigarette packs, but also banning TV advertising of cigarettes.


I guess, banned should be used in that sentence. Banning is looking more present tense in this context.

Correct:- In 1971, the US government not only put warnings on cigarette packs but also banned TV advertising of cigarettes.


Yes, it should be ‘banned’, unless you’ve cut the sentence short.
