Concrete Column Design - Tie Spacing

Hello,

RAM Concrete Column module requires a closer tie spacing near the top of column sighting the ACI 318-14 10.6.2.1/10.6.2.2.  When checking the analysis results, the shear Vu does not exceed 0.5xPhixVc for any load combination. Question: Why RAM is giving the warning the bar spacing is larger than the code limit when the applied shear, Vu is less than 0.5xPhixVc? See snip below.

Thanks,

Shahid
