Sitemap issue: 90% of links = crawled – currently not indexed | Professional help needed

Hello,

I am experiencing troubles with getting my sitemap indexed in GSC.

For most pages I get the following error: crawled – currently not indexed.

Site is +1 y.o. However, I only submitted the sitemap 2 months ago.

My website is ladykiller.nl.  My sitemap can be found here: ladykiller.nl/sitemap_index.xml

( Active links remove by Mod )

I have used yoast plugin to generate the sitemap.

Can anybody help me out regarding this issue?

Service can be paid.

All help is highly appreciated!

Warm regards,

John
