Came across a bug with Structures

Was playing around with one of my blueprint that has a structure and i made another structure and added it into the base struct called “VLDStruct”. But when i compiled i got an error and saw the base struct was missing on the Variable list and it was greyed out so i right-clicked on it to create the variable again but it didnt show up. So i took off the second structure from the base structure and compiled and got the variable to show up again but with 2 more of the same variable but iwth ERROR on it and cant delete it.
