SOLVED (kind of) Texture Groups - "Border Size" setting won't change

[HNM]

I'm trying to fit 2 sprites (128 x 256) on a single 256 x 256 texture page using texture groups. The default border size is set to 2 and will simply not save any other value, it always switches back to 2. I couldn't find any answers online. Is it a bug, or am I missing something?

Edit: So I uninstalled and deleted everything except my projects, reinstalled, and it seems to save the correct value if I insist a bit...

Dont know if it's a bug, but I get this behavior too, but only on the default group. Any created group works fine for me.

Any group I create acts the same. I also tried a different project on a different machine and the same thing happens.

Hate to revive this old thread but I had this issue and found a short term solution.
I'm going to post it here so that anyone else having this issue can 'fix' it.

!WARNING! : MAKE SURE YOU CREATE BACKUPS BEFORE DOING THIS JUST IN CASE SOMETHING GOES WRONG!

You need to find your project/solution file (with the file extension .yyp for GMS2)
You then need to open this with a Text Editor (Notepad works fine) but make sure you don't make the text editor the default for opening it
Scroll to near the bottom and you should see a section for texture groups. It's human readable for the most part (as shown in the attachment) and you can simply adjust the raw values there, save it and try opening it with GMS2.

[Discovered I can't attach an image but here's what it looks like]

"TextureGroups": [
    {"isScaled":true,"autocrop":true,"border":2,"mipsToGenerate":0,"groupParent":null,"targets":-1,"resourceVersion":"1.3","name":"Default","resourceType":"GMTextureGroup",},
    {"isScaled":true,"autocrop":true,"border":2,"mipsToGenerate":0,"groupParent":null,"targets":-1,"resourceVersion":"1.3","name":"Backdrops","resourceType":"GMTextureGroup",},
    {"isScaled":true,"autocrop":true,"border":2,"mipsToGenerate":0,"groupParent":null,"targets":-1,"resourceVersion":"1.3","name":"Fonts","resourceType":"GMTextureGroup",},
    {"isScaled":true,"autocrop":false,"border":2,"mipsToGenerate":0,"groupParent":null,"targets":-1,"resourceVersion":"1.3","name":"Main_Assets","resourceType":"GMTextureGroup",},
  ],

!AGAIN MAKE SURE YOU CREATE BACKUPS BEFORE DOING THIS JUST IN CASE SOMETHING GOES WRONG!

Hey I had the same problem and got it working.

Instead of using the Up/Down arrows to change the border size, click on the number 2 and then use your keyboard to change it to another number.
