In your initial post you said "He then sent them an email with the correct SOC code." Is he = case worker?
Occupation codes
11. The Standard Occupational Classification (SOC) codes are based on the SOC 2010 system designed by the Office for National Statistics, except where otherwise stated. This system is designed to cover all possible jobs.
12. References to “job” refer to the most appropriate match for the job in question, as it appears in the tables in this Appendix. The job description must correlate with the most appropriate match, according to the SOC 2010 system. The example job tasks and related job titles listed in Tables 1 to 4 are taken from guidance published by the Office for National Statistics. Further guidance on jobs in Tables 5 and 6 is available from the guidance published on the Office for National Statistics website. The Home Office will apply the most appropriate match based on the job description in an application, even if this is not the match stated by the applicant or their Sponsor.

Check the last sentence... HO will apply the most appropriate match based on the job description, so I assume the case worker has clarified about the right soc code? If that's the case, you need to reapply with suggested soc code and make sure the salary, etc. requirements are met.
My advice is based on personal research/experience, so pls check relevant UKVI sources.
