Hello, this one looks like it’s going to be another linguistic thriller! Help with the following would be appreciated! Thanks in advance!

14a Union when people follow church teaching at first ( 6 ) : C?M???
20a Quiet electronic piano follows etude’s introduction ( 6 ) : M?R???
25a Affectedly theatrical cases try undergoing plastic surgery ( 8 ) : AC???TS?
31a Grass to finally come to Spain ( 6 ) : T?A???

3d Directors slip up after arbitrator over pieces of work ( 9 ) :??F?RRA??
5d Famous entertainer transforming Charlie into Karen ( on the outside ) ( 5 ) : ????H
23d Political prisoner disturbed Aunt Dee ( 6 : ?????U)

14 Cement, union. CE, church, Men, people and T(eaching)
20 Sheep - Sh, quiet, E(tude) and EP< elctronic piano. Remember the wording in the preamble

[Neveracrossword]

23 A political prisoner - the word should be known to you! Take one letter from the last two words in the clue(remembering the extra letter info).

£ D Your A is wrong

[Neveracrossword]

25 Simply an anagram - I thought you'd have spotted it! It means 'affectedly theatrical'.

[Neveracrossword]

31 Your A is wrong
5 D Your H is wrong.

Sorry, the 15.37 comment was meant to be 3D...

[Neveracrossword]

In 20 A, your R is wrong (for the thematic word).

Matakari, hope those helped and that you have fixed the bits where you went astray. I think you'll have far fewer problems with this month's Genius - it was fun, but definitely easier!

31a TO + '(com)E' + TO + E (for Spain).
3d for the last 3 letters of the answer it's ER[g]S ('pieces of work') with the 'g' extra.
5d The entertainer performs in a circus - take away the first letter 'c' (for Charlie) and replace with K(are)N - def 'famous'/notable.

[ProfessorMaisie]

...for that last one the 2nd letter of the circus entertainer is extra ['l'].

Thanks, ProfessorMaisie, I'm leaving this one alone for a while.
