Attack speed variable set incorrectly in latest snapshot MCreator EAP 2019.5 b46321

I tried posting this on the bug tracker but it seems we are only allowed to post 1 bug report every 2 days so if you find more then one bug you need to either wait 2 days  each time to post each one or group them together....

Here is the issue i wanted to set the attack speed to 4.9 but when i look at the code mcreator sets it to 

}, 3, -4.9F, new Item.Properties().group(ItemGroup.COMBAT)) {
        }.setRegistryName("plasticsword"));

which when loaded into the game sets the attack speed to -0.9

If i make changes to this and change

}, 3, -4.9F, new Item.Properties().group(ItemGroup.COMBAT)) {
        }.setRegistryName("plasticsword"));

to 

}, 3, 4.9F, new Item.Properties().group(ItemGroup.COMBAT)) {
        }.setRegistryName("plasticsword"));

and save and then run minecraft again the calculations are incorrect in settings the attack speed which will set it to attack speed of 8.9

but if i set it to 

}, 3, 0.9F, new Item.Properties().group(ItemGroup.COMBAT)) {
        }.setRegistryName("plasticsword"));

and save and then run minecraft again it finally is set correctly to the attack speed of 4.9 like i originally want it to be set

Here are a few screen shots to show what is going on
