Question about backlink be google indexed.

I use RankerX with a lot of Kontent Machine made articles with backlinks sent out about 5500 for 6 site I am SEOing.
Each article is only use 5 times.
Indexr has two InstantLinkIndexer and Indexification.
But for now only about 100 backlinks is indexed I tested it in scrapebox.
I sent some link 4 days ago,some 3 days ago.....

Do I just need to wait more days or somthing is wrong?
I don't know how many day will get a good ratio for backlinks be indexed.
Thanks.

doing something wrong? you are suppose to send good backlinks not low quality.

So,do I write 10 article about 100~300 words and use them instead konent machine?And sent backlinks with these 10 articles with many times?Why it is low quality?
