Hi @rlush4F88G
From the screenshots, its looks like you are using the AutoCAD electrical demo Title Block.
If you explode the title block, you will notice that TITLE 5 and TITLE 6 attribute doesn't exist by default.

Unless of course you have modified the block and added the extra attributes.
Since you mentioned that you are just getting started with AutoCAD electrical in the previous thread, Here is breakdown of both the .WDT and _wdtitle.WDL files:
ProjectName_wdtitle.wdl file give meaningful title names to LINEX Labels while mapping attributes or updating Title Block.
You have got this file working correctly, See how Update Title Block command is showing you Title 1: to Title 6: headers and then goes back to LINE7 and so on...

See this Autodesk reference to understand more about the .wdl files.

.WDT file contains the actual mapping of what attributes in your Title Block should be connected to what project description.
Now this sometimes gets a little confusing for new users, There are 2 ways to map attributes.
Method 1 is to use a .wdt text file.
Method 2 is to add an invisible WD_TB attribute in your title block.

When you run Title Block update command, AutoCAD Electrical will try to locate a WD_TB attribute to read the mapping, If it cannot locate it, it will look for the .wdt file to get mapping.
Now if you have both defined differently, It will always default to the WD_TB attribute method first. (Default is Method 2).
Note that the AutoCAD Electrical Template in demo Project by default has the WD_TB attribute and that probably why it is ignoring your .wdt setup.
See this Autodesk reference to understand more about the .wdt files.

I am more of a fan of using a ProjectName.wdt file, that is Method 1 but this will require you to delete the WD_TB attribute from your Title Block and drawing files if it exists so AutoCAD doesn't default to Method 2.
Here is how you can setup Option 2 - Title Block Mapping using AutoCAD Electrical AESETUPTITLEBLOCK command instead of modifying the WDT file manually in a text editor.
1. Run the AESETUPTITLEBLOCK command.

2. Select the <Project> .WDT file

3. If .WDT file exists already, click Edit

4. Click Pick Block and select your Title Block

5. Map the attributes using Drop-Down and click OK.

6. Run Title Block Update command

7. All the selected attributes are updated.

8. Command Line prints all the steps, It tried to look for a WD_TB attribute and couldn't find it and then it read the .wdt file for attribute mapping and updated the Title Block.

Now I would advise doing it on fresh project, Using Purge command to clean up old blocks and Swap/Update command to reimport the modified TitleBlock.
I know this can be a lot if you are just getting started with AutoCAD electrical. Feel Free to post more questions.
Happy Drafting!
