The program restricts the nail spacings available for selection to be at least 100 comply with O86 9.4.5.5 a) when you have indicated in the design settings you want the program to apply these material restrictions. However, it does so even when you have indicated in the Hold-down configuration in Wall Input view that hold-downs are on all segments, so that Jhd cannot be less than one, as 9.4.5.5 stipulates.
It is likely that the program applies other restrictions on nail size and sheathing capacity in this case as well.
It was possible to get around this problem by changing the design setting so that materials are not restricted; however this affected all walls, even those that have anchorages.
This has been corrected and the program does not apply material restrictions to walls that have hold-downs on all segments.
