Log chain table selection selects nothing

[goddard@…]

The following bug report has been submitted:
Platform:        macOS-10.15.7-x86_64-i386-64bit
ChimeraX Version: 1.2.dev202012310239 (2020-12-31 02:39:02 UTC)
Description
open 6pt2

then click on chain A in Log chain table to select chain A.  It selects nothing and issues the command

select #2/A:999-329

that shows why residue 999-329.  Oops.  Likewise chain B selects nothing.
