Centos 8 BIRD 2.0.6 issue with rt_tables parsing

Hello BIRD users. Recently I have upgraded one of our router to Centos 8 with BIRD2 and faced strange issue with rt_tables parsing. When I have custom tables named with capital letters, for example: 128 AAA 129 BBB I get error message while trying to run bird (BIRD version 2.0.6): # bird -p bird: /etc/bird.conf:1:1 Symbol already defined I'm not sure whether it is BIRD issue or Centos one, but to run BIRD I have to change at least one letter in table name to lower case, or change naming length.
