Replace if first character is number- Truncates results

I need to clean up some data (question text) where is may begin with a numeric characters (ex. 11.006.)), if true then remove everything to the left of the ".)". else display existing question as is,   However, my current attempt seems to truncate the results

What do I need to modify to handle this issue?

Thanks,

Karen

Here is my current code:

/****** Script for SelectTopNRows command from SSMS  ******/
SELECT Distinct([sub_form_question_id]),[sub_form_question_code],[sub_form_question_system_code],[sub_form_question_field_type],dbo.udf_StripHTML([question_text]) as question_textFROM [MNS_DonesafeDB].[stg].[Module_Results]
-- Where sub_form_question_id = '2916'
order by [sub_form_question_id] asc

/****** Object:  UserDefinedFunction [dbo].[udf_StripHTML]    Script Date: 12/2/2021 1:37:28 PM ******/
