Why is Jamna so against Anant-Gehna`s wedding

Can someone pls explain why all of a sudden Jamna has turned against Gehna and doesn`t want Anant to marry Gehna? She used to love Gehna so dearly, like a mother and support her protectively, now what`s caused this abrupt change for the worse? Any suggestions? So now again we can expect Saas-Bahu drama btween Jamna-Gehna, urggh this is nothing like the first season of SNS, nothing at all, I am already quite disappointed with the departure of the Modi family from the show as it is and now the CVs are making me feel worse by tarnishing and ruining the storyline and plot, blood hell!!

She liked Gehna as a servant only not as her own bahu . that too 7th pass Gehna for a person who did masters at London 

Jamuna told the reason. She supported her & brought her up as her daughter. But she wanted an educated & homely DIL. Gehna is only an 8th pass.

She wanted an educated bahu for her laadla Anant. Dont agree with her + Radhika's behavior with Genha now tho since Gehna did not ask for the shaadi @ all.
