Check the version of libicu that your Linux is using.
That locale format requires version 54 or later.
(My up-to-date CentOS 7.7 for example is still using version 50 and the EDB Windows binaries include version 53).
In another thread about ICU problems, Daniel Verite explained that in more detail:

In your case I guess, it should be
locale = 'en-US@colStrength=secondary'
