The disc works OK as far as discing up the dirt. The problem is; it moves dirt to the center of the disc in windrow fashion. Then a pain to level out again.
As your Disc is cutting satisfactorily, your center mound problem is result of imperfect gang adjustments.
1) The rear gangs throw soil inward. Too closely spaced rear gangs create the objectionable windrow. The faster you Disc, the more soil is thrown inward, worsening the center windrow.
You need to space your rear gangs farther apart. Rear gangs should be spaced a little less than pan diameter apart. If you have 20" pans, trial space rear gangs 18" apart. Creating space between rear gangs a little less than pan diameter will ameliorate or terminate objectionable windrow.
Moving gangs farther apart usually requires loosening several U-bolts then sliding gang assemblies outward on the frame. Lubricating frame, a mallet and sometimes a dowel to "encourage" friction/dust break and movement may assist.
2) Decreasing the gang angle of rear gangs will also decrease center collection. Rear "smoothing" gangs should be first adjusted two increments less aggressively than front "cutting" gangs. Then trial other increments.
