IPSec policy is inactive on 6.43.8

I have configured an IPSec with 449 policies on Mikrotik CCR1036 with 6.37.5 OS.

Than I have exported the ipsec policy into file. After importing the file into other MikroTik with 6.43.8, from 110 to 449 policies are becomes inactive (red).
Or if I upgrade the 6.37.5 to 6.43.8 or 6.43.12 (stable) some policies becomes inactive (red) (See the screenshot).

After changing the sa-dst-address or dst-address prefix from /29 to /28, the policy becomes active. But after rebooting the result is the same, becomes inactive.

Help, please..

Unfortunately, it is an issue in 6.43.8-6.43.12 versions. Please use a different RouterOS version while we fix the issue in “stable” release channel.

What’s new in 6.44beta61 (2019-Jan-17 13:24):

*) ipsec - fixed all policies not getting installed after startup (introduced in v6.43.8);

Will wait…Thanks..
