SmartConnect configuration problem / AXI master tie-off

I am using vivado 2019.1 and an UltraScale+ SoC.

I am using a Video Mixer block configured for 3 overlay layers. Configuring for overlay layers creates an AXI master output on the Video Mixer block for each such layer.

At the beginning, I ignored the AXI master outs on this block, but design validation threw some warnings, so I ran the AXI masters to a SmartConnect and routed that back to my PS block for the sake of tying off everything. However, with that done, get the following critical warnings:

  •  [xilinx.com:ip:smartconnect:1.0-1] top_smartconnect_0_0: RUSER_WIDTH (1) of S00_AXI must be integer number of bits per byte of RDATA (64).
    [xilinx.com:ip:smartconnect:1.0-1] top_smartconnect_0_0: WUSER_WIDTH (1) of S00_AXI must be integer number of bits per byte of WDATA (64).
    [xilinx.com:ip:smartconnect:1.0-1] top_smartconnect_0_0: RUSER_WIDTH (1) of S01_AXI must be integer number of bits per byte of RDATA (64).
    [xilinx.com:ip:smartconnect:1.0-1] top_smartconnect_0_0: WUSER_WIDTH (1) of S01_AXI must be integer number of bits per byte of WDATA (64).
    [xilinx.com:ip:smartconnect:1.0-1] top_smartconnect_0_0: RUSER_WIDTH (1) of S02_AXI must be integer number of bits per byte of RDATA (64).
    [xilinx.com:ip:smartconnect:1.0-1] top_smartconnect_0_0: WUSER_WIDTH (1) of S02_AXI must be integer number of bits per byte of WDATA (64).

This is pretty cryptic? What does it mean, and how can I fix it?

(I already tried manually overriding the data widths in the SmartConnect config screen, but not of my changes stick after I hit OK.)
