FIXINIT and the house rule "Combat: Roll init each round" do not play nice together. The other effects, AFTERTURN, BEFORETURN, and SHARETURN all keep the correct initiative when it is re-rolled at the start each round. However, FIXINIT does not, a creature with this effect on it seems to roll initiative as normal, though it cannot be adjusted manually or rerolled from the sheet. Changing the number on the effect on the CT resets the initiative to the correct number, as does toggling the effect to 'SKIP' or 'OFF' then back to 'ON'. The only exception to this is if "Combat: Auto NPC initiative" is set to 'Roll All'. In that case it places the creature with the FIXINIT effect into the correct order on the CT (for example with FIXINIT: 20 it will put anything with an initiative above 20 before it on the combat tracker, and those with lower initiatives under it), but it displays the initiative as 10000 (maybe bigger, but it cuts off). Also, the turn marker will be on the creature with FIXINIT, even if other creatures have a higher initiative. Interestingly enough the same behavior occurs for both PCs and NPCs with FIXINIT.
