I removed your personal information from the attachment. You can repost it if you want but the Internet lasts a long time.
Like the poster in the other thread, my cursor simply disappears. I have no explanation for this. I have never used blank undefined fields like this. For some reason, perhaps that these are not defined fields but simply blank, your fields do not shade even when selected or when "always" is used as the option. You should not be using Word with field codes displayed. That is for development of forms and for troubleshooting.
When appropriate, I have used Macrobutton Prompt fields. Those do work in all versions of Word since at least Word 97.
I think MacroButton Prompts are great; in my opinion, they have been superceded by Content Controls for most purposes. Content Controls are much easier to maintain for most people.
Attached is your form, with some simple Content Controls at the start. Those that should be in a table are in a borderless table. I selected the area with the Content Controls and "grouped" them. You can use the Tab key to move from one to the other.
