Downgrade 6.35.2

Hi, I’m having problems in 6.35.2 and want to downgrade to 6.32.4, but isn’t possible.
“omitting package routeros-mipsbe-6.32.4: newer package routeros-mipsbe-6.35.2 is already installed”

any way to bypass this?

many clients appear with 00: mac address in arp after the update. in 6.28 it’s ok.
