pgAdmin4 - Fetching Type Error

I'm running pgAdmin4v1.1 (server version) on top of CentOS 6.8

Version1.1

Every time I try to SELECT any data from any table I get errors like these
(picture attached):

ERROR: column "slug,avail" does not exist LINE 1: ...e(oid,null) as typname
FROM pg_type WHERE oid IN (slug,avail... ^

ERROR: column "raw_targets" does not exist LINE 1: ...e(oid,null) as
typname FROM pg_type WHERE oid IN (raw_target... ^

From padmin4.log file:
