Word Document Style Uniformity

The word document has heading 1 to 5, Some of the heading styles have more space and some less space, I want them to have uniform space after the section number

Note - I want urgently so when you are bidding for this project, I will need corrected sample file attached above. I want to see whether I will get the desired result from you or not.

Example: 1. Heading and 2.1.3 Heading 3

In the above example Heading 3 has more spaces after the section number.

Tasks,

Complete the formatting of the styles for heading 1 to heading 5 with two spaces after each section number in style. The style format should be updated so that any new heading will automatically get updated base on the previous heading. Meaning if heading one start with section number 1. then the sub heading (heading 2) should start with section number 1.1. etc.

Make sure the Table of contents will also have heading such as List of Figures and List of Tables there heading should be in all caps like the TOC in the document.
Issues int he attached document.

In the attached document Document_Styling_old.docx the heading 1 and heading 2 look okay with good spacing between the section number and heading title but for heading 3 there is extra spaces added between the section number and the for heading

Please try to make the spaces between the section number and the heading title uniform (2 spaces is recommended). Also make sure the sequence number of the sections are correct.
