I do not understand why does the meld function mixes different sets of indices. For example in the following example :


ex1 := T^{a} T _{a} + T^{i} T _{i};

The output is

2 T^{a} T _{a}

whereas I was not expecting the meld function to do anything. Can someone gives me an hand on this, please ?

closed with the note: This works fine with the current version !

This works as intended on my installation of Cadabra 2.3.8. Can you try that version please and let me know whether the problem persists?
