utool2: slow import

Dear all
This week I got my U-track X32 and I’m very happy with this card.
The only thing is the slow export off the Utool V2, I make an export with old wav tracks.
For 24 tracks with 13 Gb data it took about 5 a 6 hours. Then I found this post and install V1.1.47 on the same laptop and now the same project is finished in 9 mins 16 sec.
What do I wrong, ore when will this be fixed

Greetings Peter Visscher
