Does new LCA need to filed after promotion?

My H1B got approved in 2021 while I was in position ‘A’. And while filing LCA for position ‘A’, they filed it using ‘15-1131’ SOC code which is ‘Computer Programmers’ and does not require any degree or experience.
I recently got promoted to position ‘X’ (suppose). I found for position ‘X’ they had filed LCA and got the prevailing wage as 100(suppose). But I am now in position ‘X’ but getting paid 90. Do I need to file new LCA as my position changed?

PS: The job description has not changed more than 50% from ‘A’ to ‘X’. In this case what needs to be done? Or nothing to be done?

Thank you any suggestions and comments.
