Steps to reproduce:

• create a BKS_V1 keystore or create a BKS keystore and convert it to BKS_V1
• inspect it with Keystore Report. It shows BKS_V1
• Close Portecle.
• Open the keystore again and inspect it with Keystore Report. It shows BKS (even though it actually is BKS_V1, as I could confirm by testing with an older Bouncycastle version).

Maybe there is a missing check of the STORE_VERSION.
Version 0 for BKS_V1, higher for BKS.
