SoapUI v. 5.5.0: Load Test runs HTTP DELETE instead of PATCH

Hi,

I have a TestCase with multiple steps including (among others) an REST HTTP DELETE and than a PATCH command. 

It runs fine when I run the TestCase standalone:

...

Wed May 22 21:58:53 CEST 2019:DEBUG:Sending request: DELETE /api/v1/shopping-carts/0287038cc7744fe5950d5bb10707ebdd/items/20 HTTP/1.1

Wed May 22 21:58:53 CEST 2019:DEBUG:Stale connection check

...

When I run the same in Load Test, it runs HTTP DELETE instead of PATCH also. What could be the problem?
