I can't find the corresponding change in the gds data at $PDK_ROOT/$PDK/libs.ref/sky130_fd_io/gds/sky130_ef_io.gds for volare pdk versions after that. The tapeout data for 2311 does not contain metal3 resistors in those cells.
This causes an mismatch in all LVS checks that includes chip_io and its variants.
