Looking at the output you shared of the tags on pastebin, Im actually surprised any of the clones worked given that their UIDs are different. However, the likely scenario is that there is some identifier the reader uses instead within the data blocks, probably in 1-5 would be my guess.
The dumps all had the first 6 (0-5) sectors without data since the keys werent used thus they couldnt be read. This is where I’m thinking your issue probably lies but its hard to say without seeing the data contained within.
Since you are using a phone (and MCT) to write to the cards you limit yourself to one type of magic Mifare Classic Card. The type of card that supports being wrote by a phone (and does not accept backdoor commands) is a gen2. On a review of the first Aliexpress link, it does seem that these cards support changing the UID/block 0 using MCT.
I would suggest if you are interested in doing more RFID and/or more complex operations then a Proxmark3 Easy would be a very necessary tool.

Given the above information, its hard to accurately advise where things have went awry. As a preliminary guess and suggestion as to what the issue may be would be to compare sectors 0-5 of the original card to any clones you make. In addition, you should also be cloning the UID of the original to any of the clones to make a 1-1 duplicate.
Ensuring these are the same may correct the issue you are facing.
