FP4 dual SIM problems

My FP4 5G does not work properly when there are two SIMs inserted. It will not prioritise the eSIM for calls, data and texts. It remains locked to the physical SIM and, because of this, wifi calling is also locked to the wrong SIM. The eSIM is from my main provider and therefore that is the one I wish to use as the default in the UK.
How can I resolve this problem? Has anyone else experienced this problem?
Can anyone help?
