No autofocus on Panasonic G7 with Metabones Speedbooster on Sigma 18-35

So, I'm using a Panasonic G7 with a metabones speedbooster, which is advertised to have full electronic communication with the camera body. (https://www.bhphotovideo.com/c/product/1158844-REG/metabones_mb_spef_m43_bt4_canon_ef_micro_4_3_t.html)

I also have a Sigma 18-35 which is connected to the speedbooster and has an Auto-focus mode.

Unfortunately, I am unable to get the auto-focus to work, despite enabling AF mode on the lens, and I've tried both AFS and AFC modes on the G7. I just bought the speedbooster and the lens, and they were used, so it certainly might be that one of them has an issue, and both are within the return window.

So, does anyone know what might be the issue here? Thanks in advance!
