Canonical url different between Google and Sparkle

Hello,
My site is structured using directories (my-url/EXAMPLE/).
Each directory has its own index page (my-url/EXAMPLE/index.html).
In the site parameters, I indicate https://www.mon-url/EXAMPLE/ as the reference url.
Google uses https://www.mon-url/EXAMPLE/ as the canonical url.
Sparkle declares https://www.mon-url/EXAMPLE as canonical

Google therefore considers as canonical a url that is not canonical for Sparkle.

I don’t know if this is serious for SEO, but it can’t be good.

What’s more, the site is bilingual and tools like Semrush alert me to the fact that there are redirection problems with hreflang tags.

Is there a solution?
