Hi,
Thanks for getting in touch with us.
It looks like you have two canonical tags. The first one is added by your theme we assume and the second one by Rank Math.
Please get in touch with your theme provider and ask them for instructions on how to remove the canonical tag that they are adding.
The one added by Rank Math should stay since having it once is pretty important.
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
