TH Drilling Gumbo Issues

Whilst drilling 24" / 26" hole sections with seawater& sweeps prior to switching over to DKD mud, gumbo is a major issue with it at times dislodging the DAT from the LPWHH, blocking dispersion tubes on the wellhead, stabs balled up, large accumulations around the wellhead etc etc
Anyone on the forum got similar experiences and possibly suggestions on how to facilitate drilling through these sections.
Looking at 21 previous wells yesterday there was only 2 - 3 wells when gumbo was not an issue and the only common denominator was higher ROP.
