switching from 'basic' to 'monolith' env results in error 'non-unique elements'

HI
After successfully running thingsboard in cluster using 'env=basic', i switched to 'env=monolith' and got the following error:

services.tb-monolith.ports value ['8080', '7070', '1883', '7070', '5683:5683/udp', '5685:5685/udp'] has non-unique elements

How do I go about fixing this?

duplicate of #24 seems that there is a PR waiting to be merged for fixing this #25
