I would agree. This is regarding the auto arranging of icons.
Secondly, if I understand right, you have a different issue; one or more unknown apps are making Bliss “issues” more pronounced.
First action to take would be uninstall any unnecessary apps and any which you expect might be causing the problem.
Then Settings > Apps and notifications > Show all apps > Bliss > Storage > Clear storage.
This will put all your app icons to “standard position” I suggest you leave them there. Now can you identify an app which is upsetting Bliss?
… or don’t use Bliss! 
Be aware, this advice might cause you to lose Weather widget data, if you are separately affected by that issue.
