Villagers that have trades unlocked before 1.14.4 pre 2 do not restock up to x16 x12 x4 as changed in 1.14.4 pre 2. they still restock up to x8 x6 x2

As a hack fix, you could run the comand :
/data modify ... Offers.Recipes[X].Trades set value (16/12/4)
Where in ... goes the uuID of the villager and Where X is the position of the trade you want to upgrade, and the number (16/12/4) one of those would be the correct amount of items that would be traded in newer 1.14.4 version
still not fix in pre release 6
