In researching the answer to your question, I discovered that this journal is indeed on my standalone journal list, but it is one in a fleet of journals published by the Indian Society for Education and Environment, which is on my list of questionable publishers. The standalone journal list should not duplicate journals under the publishers on my publishers list, so I have removed the journal from the standalone list.
You indicated that the journal is “indexed in ISI” but I do not see it listed in the Thomson Reuters master index here:

I am concerned that the “Indian Society for Education and Environment” is not really a society in any normal sense of the word. It appears to be an open-access publisher that presents itself as a society in order to appear more legitimate. It publishes over a dozen journals, all with very broad coverage, done in order to be able to accept more papers and therefore earn more article processing charges.
I don’t understand why the society sells subscriptions to its journals (at $400 / year) when the content is open access. This is not illegal or even close, but it seems unusual to me.
