Duplicate values binding in system configuration in Magento 2

[bojjaiah]

In my module have customer (Create and Update) setup system configuration. From that I have stored some values and it's saved (table core_config_data) correctly.

And Rendering also correctly but displaying duplicate i.e., displaying last setup values. see screen shot & logs below.

Note: Both groups are in same section. If different section it's working fine. If both groups are same section it's not working. If I create only one column with text field in two different groups then also it's working fine.

Create Setup Log

Array ( [0] => Array ( [element] => Magento 1 [field] => firstname [constant] => Constant 1 [filter] => Filter 1 ) [1] => Array ( [element] => Magento 2 [field] => middlename [constant] => Constant 2 [filter] => Filter 2 ) )

Update Setup Log

Array ( [0] => Array ( [element] => Mage [field] => updated_at [constant] => Cons [filter] => Fil ) [1] => Array ( [element] => Mage2 [field] => dob [constant] => Cons1 [filter] => Fil1 ) )

But displaying both values are same i.e., Create setup have duplicate of Update setup values.

@magento-team If different section it's working fine. If both groups are same section columns id should be different then it will be working fine otherwise it's not working.

Is it a bug?
