hi @AkisM,
Sadly, I can't reproduce your error.
I have the latest version 2019.4.4.202026 - Admin
Do you think that you can migrate to the latest version?

Could you please share your Alteryx Designer version as well as if it is admin or non-admin
Could you also share the file /sample data and a screenshot?
Best
Alteryx Admin Designer version 2018.4.3.54046 x64
