Problem importing TM into Trados Studio 2022

I am trying to import a TM from my desktop version of Trados Studio 2022 into Trados Studio Cloud. The TM on the desktop has 38,920 units, but only 14,999 get imported. It is an SDLTM file of 232MB, so well within size limits. Two smaller TMs have imported 100% OK.

What can I do? I don't want to split the TM and then have to maintain multiple TMs for the rare occasions on which I use Cloud not desktop.
