That's a fairly normal part of having a multiply redundant system. Normally you'd use a rolling* average of all the values, so as soon as you switch one system out the average should start to converge on the value from the still operating system(s).A follow-on problem must be that even if the faulty IRS is shut down, accumulated positional and attitude/directional errors will then need to be corrected.
*i.e averaged over a set period so a single spurious value doesn't cause a sharp deviation.
