Ok, it all makes sense now, you did it right with the R-0007 and then R-0008 which would turn green with TA but if no TA it would go straight to the cherry red. They added a lot of MA because they know pH rises with new plaster. So it also tanked your fill water TA. Per the NPC (see attached) you should target a TA of 80 - so you may want to discuss that with your PB however you are somewhat between a rock and a hard place because he is providing the warranty. Also, your specific plaster type may have its own start up guide provided by the mfg. Good Luck.
