If you check the references here in Researchgate and scroll down you see that your paper (among a number of others) is seen as a reference but the search engine of RG does not recognize it (so it not assigned to the right paper and author(s) here in RG).
This unfortunately happens (in my view too often). Because it is not recognized the citation does not count (at least not here in RG) while I have noticed for a number of my papers that such a citation is recognized in other indexing services like Google Scholar, Microsoft Academic (Search), Scopus, Dimensions etc.
You stumbled on one of the weak features of the RG search engine (or reference scraper tool or whatever you need to call it). Although I have to say that I noticed it the other way as well (no recognition in Google Scholar while it is registered in Researchgate). An example of the imperfection of all these kind of services I guess.
PS. I noticed that sometimes even adding a DOI to the ‘unrecognized’ reference in one of my own papers is not overcoming this problem. It is strange and annoying but I believe I read somewhere that RG is working on it. You might report it to the RG team, perhaps this helps…
Thank you for reaction . But my paper cited in two articles present in Research gate.why detect one not other.also in google schooler cited by three articles one of them not scopus.
It has something to do with the way the publisher/the journal/the individual author provides the references information. Some are picked up (by RG or Google Scholar etc.) better than others.
It is somewhat mysterious I have to agree but fact is that some references are picked up better than others.
All you can do is:
-Make an ORCID ID and include the different names of your author name as they are mentioned in publications.
-Fill in the paper/journal information (including year and so on) as detailed as possible (some journals are unfortunately not included in RG database so the journal name of the publication cannot always be included).
-Consider to use Zenodo to give a particular publication a DOI nr. when it is not assigned at the time or is simply not given (for a report, chapter and so on).
This is about the maximum you can do besides hoping that the RG search engine improves it performances when it comes to this matter and patience since Google Scholar for example solves some of these issues but only after a long time (sometimes years later...).
