Upgrade test to channel 1.8.x fails with "2 replacement chains were found"

I'm trying to run upgrade test from released Camel K operator 1.6.7 (source redhat-operators) to build 2022.3 CK2.
I observe problem in upgrade scenario (/e2e/upgrade/olm_upgrade_test.go):

• on OCP 4.10, with env
  RELEASED_IIB=registry.redhat.io/redhat/redhat-operator-index:v4.10,
  DEV_IIB=registry-proxy.engineering.redhat.com/rh-osbs/iib:261153, CAMEL_K_PREV_UPGRADE_CHANNEL=1.6.x,
  CAMEL_K_NEW_UPGRADE_CHANNEL=1.8.x

• the released operator 1.6.7 seems installed correctly - upgrade fails with following error in Subscription of Camel K operator (Conditions):

ErrorPreventedResolution a unique replacement chain within a channel is required to determine the relative order between channel entries, but 2 replacement chains were found in channel "1.8.x" of package "red-hat-camel-k": red-hat-camel-k-operator.v1.6.6...red-hat-camel-k-operator.v1.3.2, red-hat-camel-k-operator.v1.8.0...red-hat-camel-k-operator.v1.6.7-0.1655811913.p
