Honest question about the training range (Simulacrum)

Is it just me and my duo but does anyone else wish the arsenal in the simulacrum could work for multiple people at the same time like the one in the dojo or is this like a bug we have been experiencing for like 2 years, Just curious if this is just a issue with our Sims because my duo's Sim is boofed as hell where we get two different damage numbers on the same enemy and sometimes buffs never fully activate or just exist permanently or are Sims just cursed In general. Any insight if its something on our end while be grateful.
