Why does firstLineIndent have to be -20 ?

Question

Hello,i´m currently implementing a PPTX with .NET Core and Syncfusion Presentation 17.2.0.35. The PPTX is supposed to create a list with bullets. This list can have multiple levels, which the paragraph IndentLevelNumber should support. But here comes the problem: If I do not set the FirstLineIndent to -20, the text of the paragraph will continue to write under the bullet after a line break... why? I need to edit the Indent of a Bullet but it seems like FirstLineIndent has to be set to -20 and has no other effect. If it is set to -20 the text writes under each other as expected after a line break. I checked this document of yours https://help.syncfusion.com/file-formats/presentation/working-with-list And it also says I have to set it to -20. Regards.

FirstLineIndent 

FirstLineIndent property is used to set a special indent of a paragraph such as (First line indent and Hanging Indent). This property works similar to highlighted property in a Microsoft PowerPoint screenshot. 
FirstLineIndent property is act as First line indent if you set a positive value and it act as Hanging indent if you set an negative values. 


  

LeftIndent 

LeftIndent property is used to set a Before text indent of a paragraph. This property works similar to highlighted property in a Microsoft PowerPoint screenshot.  
If I do not set the FirstLineIndent to -20, the text of the paragraph will continue to write under the bullet after a line break... why?As per the Microsoft PowerPoint behavior, If we set an hanging indent 20 (FirstLineIndent = -20) to the bullet contained paragraph with some left indent values, It moves a bullet character alone in left side from a left indent value. (Paragraph remains its position). 
If we set first line indent 20 (FirstLineIndent = 20) to the bullet contained paragraph with some left indent values, It moves a first line of paragraph alone in right side from a left indent value. (Bullet character remains its position).I need to edit the Indent of a Bullet, but it seems like FirstLineIndent has to be set to -20 and has no other effect. If it is set to -20 the text writes under each other as expected after a line break.You can able to customize the indent of an bullet from a paragraph by modifying the values of our FirstLineIndent and LeftIndent properties similar to Microsoft PowerPoint.Please let us know if you need any further assistances in this.Regards,Vijayasurya A
