Ok, good detective work 👍.
Here is a video on making mass changes like that.

Please like/subscribe our channel if you haven't already.
This video will help you make all three changes.
Another option to fix the ones that have been uploaded but are not marked as such is to merely send them again.
If you want to leave /8 in your operator field in LOGic, make an ADIF file. Edit it in notepad and make the change there using REPLACE ALL:
<operator:6>KV3R/8
to
<operator:4>KV3R
Let me know if any questions.
Tnx & 73,
