"Name" is a fine name for a column and I can add multiple columns, change their order, it doesn't matter: Once I have set the sorting for the "Name" column, everything works like expected.

So your issue must have a different cause. I propose that you export your trouble causing udt and send this xml file to xmlmodule@gmail.com.

Thread Summary:

Issue:        Sometimes in the past modules sorting setting don't get used.
Cause:       Still unkown

Workaraound: Export your module and reimport it. Everything will be renewed and works fine again.

Please take care, if you update UDT prior to proper DNN version: There is a special mechinism used, that prevent database scripts to run, if the core version is not appropriate, so you can install previous UDT version over existing one without loosing functionality. Unfortunately the module version is updated anyway, and the scripts don't run on subsequent update of UDT. I recognized today, that DotNetNuke 3.3.5/4.3.5 now prevents installation of previous module versions, so I recommend the following procedure, if you previously installed an unsupported version:

• Login as Host
• Goto "SQL" in Host menu
• enter the following text in the box and hit run 

        Update {objectqualifier}ModuleDefinitions SET Version = '03.03.00' WHERE ModuleName ='DNN_UserDefinedTable'

• Install previously used version of UDT
• Install latest version of UDT
• try the module
