Double executing of the same job

I have a strange behavior for some (not all) jobs:
We have a few equally configured jobs (you can see "Bubbleroom" text on the image, we have a few more jobs with different names there. Some of them executed once, but this one executed twice without any notifications.
We have only 1 server and 1 DEFAULT queue executed as windows service.
Job each time executed from start to end without exceptions (last line is writing a log message to papertrail and this log message appears twice).
Recurring jobs page shows that it was started exactly when it should (it is true).
All jobs (24 jobs on a image) have tag to prevent concurrent executions, but

I cant understand why this happen and what should I check and how to prevent this issue?

Start with the recurring-jobs page, DEFAULT queue, Windows service setup, concurrency-prevention tags, and duplicated Papertrail log entries described in the report. Reproduce or correlate the two complete executions and determine the cause and a reliable way to prevent duplicate job runs.
