They should had used boxing ring.then what is it?
Then such fight might be ranked and recorded as am boxing fight ....
Otherwise yeah it is am boxing fight.
We had exp with some small hall type proms when they had some fights with Kickboxers using mma glowes and rules ( on paper ) and these were technically classified as mma fights.
Despite stuff guys did in cage was kickboxing...
So there's some organisators mistake because they didn't had used boxing ring...
