Limited number of genome downloads for some taxon

[mkdevesh]

I am trying to download genome of assembly level 'chromosome' for several bacterial taxon. But realized that there were less number of total genomes being downloaded. I cross-checked the number for E. coli genomes and it is 4807 as of now. here is the code used for downloading and tried 'dehydrated' option as well but the same results and then I tried 'complete' assembly level which resulted in 7,763 which is quite surprising as it should be lesser than chromosome level. And also the number is quite similar(763 and 7,763) which I have no clue why.

Now I have to question all the downloads as this has become unreliable. Please solve this issue so that it downloads the correct number of genomes at that time. Thanks
