May I know which version you are running. I've been using 11.5.4 and the behavior was to complete overwrite.
When I moved I tried on 13.x, the behavior modified to merge with the existing ones.
When I checked with F5 on this. They had said it was a behavioral change. I can get you the article number/reference number if want,
Here's the ID of it - ID 667223
It started to change from 12.1.x versions - https://techdocs.f5.com/kb/en-us/products/big-ip_ltm/releasenotes/related/relnote-supplement-bigip-12-1-3-6.html
Hope this helps.
