Frustrating issue with Multi Language website

[dpuk44]

Hi everyone, hope you're all well!

I am having some issues with a website of mine in the SERP. I have a website in English and is also available in Spanish, Italian, German and French. When I search for the brand in Google.Co.Uk the Spanish page is showing in the SERP, but I have absolutly no idea why.

Can anyone provide any advice?
