Oddity when opening Textmaker with altered normal.tmvx

[Panch]

I altered normal.tmvx minimally, changing only the font from TNRoman to Arial and the size from 10 to 12 pt. Now when I open Textmaker, I initially see a brief view of the original normal.tmvx with TNRoman and 10 pt., and then I see in a moment the altered normal.tmvx with Arial and 12 pt, which remains. I did not choose to create a new template because I did not want to have to choose an alternate template with every new document.
My question is whether this blip is normal behavior, or perhaps the blip indicates that I did not proceed entirely correctly in altering normal.tmvx. I did work with the Softmaker manual in doing this.
If I indeed altered normal.tmvx, then how it is possible that the original version still exists to make a brief appearance when I launch Textmaker? This effect is persistent, not one time. While not very problematic, I find this effect mysterious.
