pt-online-schema-change: alter not working because of pxc_strict_mode = ENFORCING

Ronny GörnerRonny Görner Current User Role Supporter
Howdy,
first, thanks to all supporting this cool piece of software.
However, we have a small issue (maybe not even a small but a major) on changing tables using Alter commands or scheme changes. This would normally result in locking the cluster, so we deciced to use pt-online-schema-change to avoid those problems.
pt-online-schema-change --execute --statistics --preserve-triggers --alter "ADD COLUMN test varchar(255) DEFAULT 1 AFTER abfragescore_id" D=webhaus_live,t=scoring_bankverb_score
results in

2020-04-07T10:06:45 Dropped triggers OK.
Not dropping the new table `webhaus_live`.`______scoring_bankverb_score_new` because --swap-tables failed.  To drop the new table, execute:
DROP TABLE IF EXISTS `webhaus_live`.`______scoring_bankverb_score_new`;
# Event  Count
# ====== =====
# INSERT    57
`webhaus_live`.`scoring_bankverb_score` was not altered.

For me, it seems, this is not working because of using ENFORCING mode in the cluster.
Is there any workaround on this to let it work?
Best to all and keep healthy,
Ronny
