I bought this and after repotting this happened overnight...

Last watered 1 month ago
Did you water the plant after reporting? And is the pot has any drainage hole?
That looks like dehydration or sunburn ?
Freddie like most Calathea are dramatic. Iā€™d prune the obvious dead leaves and water it and see if it perks up.
Like @SpiffyGonolobus and @KDkat3 said,

You should slways water after a repot. Water and let it bounce back before pruning.
