taxize had controversy outputs

I'm trying to get some aspects of the taxa classification (e.g. the class or family name) from a list of species, but when I run the function "tax_name" some species get an empty result. However, when I run the function "gnr_resolve" to the same species with the previous empty result, the package returns all matched names from different data source.

How the package could had an answer from one function, but does not have from another?

As an example, I was trying to check for the "Bufo margaritifer" specie. Which does not have the answer from tax_name function, but had at least 19 matched names from different data sources into gnr_resolve function.

example <- c("Bufo margaritifer", "Adenomera saci", "Hyla minuta")

tax_name(example, get = "class")

db query class
1 itis Bufo margaritifer NA
2 itis Adenomera saci Amphibia
3 itis Hyla minuta NA

gnr_resolve(example)
