Number of countries exceeding 32

I'm using Ares 2.0p1.

I read the guide and understood.
http://ares-developers.github.io/Ares-docs/new/sidescountries/index.html#countries
(Playable countries are max 16)

However, looking at the contents of the link below, I found that although it is incomplete, up to 32 registrations are possible.

So I registered up to 32 playable countries.

[Countries]
0=Americans ; Starts at zero because dialog returns 0 for first listing regardless of name
1=Russians
2=YuriCountry
3=Nazis
4=Korean
5=European
6=NKCN
7=TDGDI
8=China
9=Israel
10=Test1
11=Test2
12=Test3
13=Test4
14=Test5
15=Test6
16=Test7
17=Test8
18=Test9
19=Test10
20=Test11
21=Test12
22=Test13
23=Test14
24=Test15
25=Test16
26=Test17
27=Test18
28=Test19
29=Test20
30=Test21
31=Test22
32=GDI
33=Nod
34=Neutral
35=Special

However, the remaining four are the problem.
32=GDI
33=Nod
34=Neutral
35=Special
They are countries not used for play.
But deleting those from the country list causes an error.
So I left those four on the list.

As a result of the test, right now, there are no errors and there seems to be no problem.
Could this cause problems later?

By the way, I am sorry for my poor use of English.
Please answer about my question.
Thank you.
