[Potential Bug] Several drop down in a module

Hi all, I realized that if in a module, such as “Account”, there are more field DropDown connected to field DropDownDinamic the filters are no longer met.
Example
I connected to the field DropDown “Industry” the field DropDownDinamic “Sub Industry”.
Then I connected, also, the field DropDown “Type” the field DropDownDinamic “Sub Type”.

When I go to create new company the four dropdown are fully visible to all values.
When I select the value of the first curtain, such as Sector, then the values of the curtain attached are filtered corrected.
This problem does not exist when there is only one module in the dropdown linked to only one dropdowndinamic
I hope I was clear and to receive an answer, thanks

I think I can be certain that it is a bug.
When there are more DropDown the DropDownDinamic not work well. It works just the first.
I enclose picture, I hope you understand better

Just delete the second DropDown (that worked well) and the first DropDown now works well

I’m hoping for some help.
Thank you
