Foliage tool erase doesnt work

foliage tool will not allow me to erase or use lasso

this only happens in specific project

I can add foliage to landscape and sculpt no problem
i can delete one at a time

but I have a whole bunch of mushrooms I painted but they are floating in the air and not sure if i sculpted landscape after I put them down or they just didn’t get applied correctly

any ideas what would stop it from working
I can create a new level in that project and it still doesn’t work

create a new project and it works

added to project
ProceduralNature Pack 1
ultra Dynamic Sky
InfinityBladedfirelands
shroom pack 1
Water plane
Planetformer
advancedMagicfx08
the zen learning project too

any ideas would be appreciated

Hello :
Select which foliage you no need then press Shift+Left Mouse to Erase (note you should Select particular foliage in
Add Foliage Type

Same issue with me, I use UE4.26 any solution ?
