Updating Data assist pages with presets

I tried to update a page created with Webassist - Data Assist Pages.
I found the only way to update was to delete the Admin folder and files and to recreate them with the following routine.
I have a zipped preset

I open Webassist/Database/DataAssist Pages.

In the dropdown Application Type I can see preset managers I created.
I select a suitable preset manager.

I change any settings required and finish, the preset generates a new updated admin folder and files.

On Insert page the first two fields I have a Required notice. These have a yellow label which obstruct the field/box view.

I have other fields marked as Required but they do not show a label when Updated but with an Empty field box .

Can you please remind me how to change the label colour and move it from obscuring the field/box view please?
Also is there a reason why some fields do not show the required warning notice?

I attach an image to show the required notices

Many thanks
John
