Resolved Wired shapes shown when i change outline size of textmeshpro from script

i built i custom editor that allows me to change many gameobject text settings like changing the font color and adding outline and more

when i set the stroke size = 0 , everything works fun with every font i try but when i change the stoke size only default unity font works other fonts shows a weird shapes like this :

i tried changing the stroke(outline) individually from inspector and its works well so maybe i miss something on the script
this is the script

Code (CSharp):

1. public void UpdateSettings()
2. {
3.     for(int x=0;x<transform.childCount ;x++)
4.         {
5.             GameObject country = transform.GetChild(x).gameObject;
6.             country.GetComponent<SpriteRenderer>().color = countriesColor;
7.             country.transform.GetChild(0).gameObject.SetActive(showNames);
8.             if(showNames)
9.             {
10.             TextMeshProUGUI text = country.transform.GetChild(0).GetComponent<TextMeshProUGUI>();
11.             Material mat = text.fontSharedMaterial;
12.             if(fontAsset != null)
13.             {
14.             text.font = fontAsset;
15.             }
16.             if(strokeSize == 0)
17.             {
18.              
19.             }
20.             else
21.             {
22.                 mat.shaderKeywords = new string[]{"OUTLINE_ON"};
23.             }
24.             text.color = fontColor;
25.             text.fontStyle = fontStyle;
26.             text.outlineWidth = strokeSize;
27.             text.outlineColor = strokeColor;
28.             text.text = country.name;
29.             }
30.         }
31.      
32. }

note : i am using unity 2019.4
