SetCalcBorder OOME 4.1 Listing 415. p.467 doesn't give me the same picture

SetCalcBorder OOME 4.1 Listing 415. p.467 doesn’t give me the same picture of cells when run.

I’m running:
Version: 7.4.7.2 / LibreOffice Community
Build ID: 40(Build:2)
CPU threads: 4; OS: Linux 6.1; UI render: default; VCL: x11
Locale: en-US (C); UI: en-US
Raspbian package version: 4:7.4.7-1+rpi1+deb12u5
Calc: threaded

I’m wondering if others see the same two vertical lines or is my system settings such that I don’t see what Pitonyak saw.

All sugestions welcome.
Thanks,
Mike

I only can see two vertical red (left) lines in b2 > b6 and c2 > c6
