I have a script that takes in a csv with TagPath and then columns of the names of UDT parameters to set using system.tag.configure, however when I use it, the parameters are added as expected but the UDT `tagType` is converted to an `AtomicTag` where before the configure it was a `UdtInstance`.

As a single example, this is what I’m passing as the “tags” array into the configure function:

```auto
tag = {'name': '01', 'parameters': {'Description': {'dataType': 'String', 'value': 'Pump Station 1'}, 'Alarm_ParentPath': {'dataType': 'String', 'value': 'Hellow'}, 'Alarm_Area': {'dataType': 'String', 'value': 'Wine Delivery'}}}

system.tag.configure(basePath = tagParentPath, tags = [tag], collisionPolicy = 'm')

```

This does seem like a bug. I’ve opened a ticket. In the mean time always including `'tagType': 'UdtInstance'` should allow it to persist.

Yep that’s what I did, works well with that in it. Very useful function!
