Is having the same URL in several sitemaps a problem for google?

[lcourse]

We have 30 sitemaps, one for each language version of our site. About 5000 pages per sitemap.
To get a better idea on which pages google is not indexing, I thought about quickly generating sitemaps by page cagetories to see if there are any patterns.

Any problems if I submit now new additional sitemaps dividing all our pages by product page, considering that the same pages are already in our existing sitemaps we submitted in the search console. So having same URL in more than 1 sitemap would be a problem?

As a side note, we observed when adding a sitemap index that google search console in its count of total indexed pages, now counts every page twice since we submitted both the sitemap index and the individual sitemaps, so search console does not recognize in count that sitemaps in sitemaps index are identical to the ones we submitted individually in search console.

not sure, you may have misunderstood the question.

to clarify: all pages are one domain.
including all pages in one sitemap would exceed googles recommendation of max. number of pages per sitemap and we like to see breakdown of how far google is indexing our different language versions.
