Weird Merge of Contacts

I got a weird behavior on my Samsung S7 Nougat dual sim Phone merging two different contacts entry. Out of the blues, I noticed that some contacts have disappeared but I realized that those contacts got merged somehow with others. As you see in the example in the screenshot, by showing this account Tawfik, you can see two numbers while it should be only one, while Mougy contact every has disappeared!! the first number is for tawfyk while the other was supposed to be for mougy!!! By choosing Edit contact, I found out as you see there are TWO google accounts attached to tawfyk, and by typing each tab you will find one with the right Tawfik number while in the next tab you find Mougy as name with mougy number!!!!

Any justification!?!!??!?!

It’s worth mentioning that I got Parallel Space App installed on my phone for dual Whatsapp accounts.

any advice
