Dear Essam Al-Zaini Looking at your Google Scholar profile I think the h-index here on RG is correct https://scholar.google.com/citations?user=c6VBAkMAAAAJ&hl=nl&oi=sra
It has to do with the definition of the h-index https://mdanderson.libanswers.com/faq/26221#:~:text=The%20h%2Dindex%20is%20calculated,cited%20at%20least%2017%20times. . Although you have a couple of publications that gathered way more citations than six it is because of this definition that you have six publications with at least six citations (it is something different than for example the average citations per publication).
I would say keep up the good work and don't worry to much about these type of metrics.

click on references and you see the ‘problem’

Dear Rob keller, thanks for caring by addressing this issue. However Scopus citations should be detectable in RG cause it has wider search engine as I think.
