Think I may have answered my own question!!! Whilst playing around, I realised that after adding some more costs in that the updated tasks needed rebaselining in order for the calculations to be done correctly.
When using Tools/Tracking/ Set Baseline then choosing "selected tasks", it offers an option to "Roll up Baselines" and select "To all summary tasks". When I checked this box, the SPI then recalculated the summary bar, and this now shows an SPI of 0.89 (the two costed tasks below have SPIs of 0.8 and 1 hence 0.89 is in the right "ball park") instead of the previous 1.94.

Fingers crossed this has resolved the issue!!
