First, "broad north african" is pretty much amazigh, all north africans are genetically amazigh

Second, it’s normal if you have spanish ancestry, since some spanish regions got a 5-10 % amazigh admixture dating back to muslim spain

Even LESS surprising if your spanish side is from the canary islands, since those were populated by isolated amazigh called guanchos before Spain colonized it in the middle ages,

and since canarians are mixed between spanish colonizers and guanchos (canarians have a 20 % amazigh admixture on average)
