Try to send yourself your satoshis to consolidate.
Thanks.
#Memo should just have a 'Consolidate' button that creates the maximal possible consolidation transaction, or at least give the advice you did when they display the error.
Well, it costs miner fees, so memo keeps it fragmented. When I consolidated mine (in Electron Cash) every single like was its own coin still. Was a pretty big TX to consolidate.
I think for most things it doesn't matter. If it matters for SLP tokens, then they prolly could update the code to first do a consolidation to make a coin big enough then generate.
