Different first authors having same surnames aggregated together in acmtog

[yutanoma]

I hope this finds you well.

In my manuscript in \documentclass[acmtog,nonacm,anonymous,review]{acmart}, I found out that three papers written by different first authors (Hsueh-Ti Derek Liu, Shaohui Liu, Shibo Liu) were all aggregated as [Liu et al. 2021, 2024, 2020].

I thought that this might give the misconception that these three authors are identical, and would be better if it was grouped separately, like [Liu et al. 2021, Liu et al. 2024, Liu et al. 2020].

The latex code and screenshot are below.

Multiple Lius are aggregated even though they are all different Lius \cite{Liu2020DIST, Liu2021SurfaceMultigrid, Liu2024SmoothBijective}

For reference, below are the three papers:
