Issues and Bug Reporting

Summary

When copying a value from an array to another one, the values get linked, making this not usable because it creates a behavior where you could delete data from the other one without knowing.

UI/Tools

Steps to Reproduce

Have two device with and array of same custom data for example a concrete class.
Copy and paste the values from one to another.
Values get linked, to check this, modify 1 of the arrays, check the other one and you would be able to see them changed.

Values should be copied from one to another, but not be linked. So changes in one should not change the other one.

Arrays get linked, changing one, affects the other one.
