Date of Last Delivery incorrect in EKEK (sometimes)

Hello!

When I go into ME39 and into the Release Documents, I have correct dates for Last GR (EKEK-LWEDT) but for Last Delivery, it shows me the date (and number) of what was probably the first Delivery received for that contract. (EKEK-LFDKD / LFNKD)

See picture below, notice the inconsistencies. The first wrong case happened in the release generated December 6th 2013, as shown in picture below.

Then starts happening more often in January 2014, and surprisingly in the release generated April 3rh, 2014 the number is correct...

I have already checked these 2 notes, mentioned in the only post about this issue (from 2011), but they are already implemented in my system, since we have 604, SP 14

1337084 Release header contains doc. date instead of delivery date

1309001 Incorrect date for last goods receipt in sched. agreement

Any help would be greatly appreciated!

Thanks!
