I'm sorry. It's me again.

I'm trying to create AutoSuggest (English to Japanese) from my huge master TM (translation units:more than 1,700,000) using Studio 2017.

I heard there should be no upper limit of TUs to be imported from TM into AutoSuggest if there is enough space in its PC to save the AutoSuggest.

But in my case, the maximum TU to be imported into AutoSuggest is set at  531,382 TUs as a default in the AutoSuggest Creating process, though my PC seems to have enough space, that is, 123 GB blank space out of 250 GB for a folder to save the TM and its AutoSuggest. I also tried to create the AutoSuggest from the same TM using my external Hard Disc (900GB blank space out of 2TB). Still failed. Always limited to 351,382 TUs.

What's wrong?

And every time I tried to create the AutoSuggest, it automatically minimized my TM's TU size to 521,382 TUs, 1/3 of the original TM size. I have a master tmx file for this huge TM, so I can create the huge TM again, which has more than 1,700,000 TUs. But unless I find the solution, I can't create the AutoSuggest without minimizing my master TM of the Studio 2017.

Moreover, the created AutoSugget is not displayed on the Edit screen using the minimized TM.

My PC info:

Microsoft Surface Pro 3 (250 GB), CPU: Intel Core i7, RAM:8GB, Windows 8.1 Pro(64 bit), External HD: 2TB, Office 365

PC interface language:Japanese
Language pair: English to Japanese

Nearly all the items are check-marked on the AutoSuggest page <- Option <- File of Studio 2017.

What should I do? What am I missing here? Any suggestion?

Thank you in advance!
