Studio 5000 v32 SQI instruction problems

[Carl985]

Hi folks I'm currently upgrading a control system that's nearly 20 years old from a 1756-L61 last programmed using version 20 logix5000 to a 1756-L82e using v32 studio 5000/logix designer.
I'm having issues with the fault handler routine was working with no issues in logix 5000.
The faults are stored in R_Fault1 dint(4) array they are the copied using cop source R_Fault1[0] dest D_FLT_Code1[0] length 4 then it passes through an SQI instruction which sets the relevant fault. My issues is that for every fault in the first word R_Fault1[0].0 to R_Fault1[0].31 its works fine but for anything else eg R_Fault1[2].22 it just skips past it. As I said earlier it was working fine in v20 its just started happening after changing to v32 I have attached a picture of the SQI. Thanks for your advice in advance

Update

Hi folks just an update: so after my problem bugging me all night I popped into work on Saturday afternoon and started having a play around and I found out the following.
The sqi instruction is not comparing the source and array unless I cycle through the length as follows, if I have a fault in dint 1 when the length is set to 4 it will work once then if I set the fault dint back to 0 and then trigger the fault again the sqi won't compare again until I change the length from 4 to 1 etc does anybody no why this would be
