when I use the "Get collection ranking" API (link:https://docs.nftgo.io/reference/get_collection_ranking_eth_v1_market_rank_collection__time_range__get-1) to get NFT collections' ranking info, I find that the function returns to me a lot repeated collection.
In my python script

I set {offset} number incremented from 1 and {limit} =50 by default. But the result is that I get too many repeated collections info.
Is this a BUG or my operational error?
