Minecart Mania question

Hey guys,

after reading the forum rules and seeing other threads like this, I hope it is okay to seek help in this forum, since the MM thread is closed for quite some time now and thanks to its popularity, support never came through.
My question is related to control blocks. I noticed, that platform blocks are unable to fetch players, if minecarts pass too fast over them. You will get the message "Tap in a direction yadada" but still be where you were and the minecart continues its travel. Hence I tried slowing down minecarts. In initial testings it worked fine. I slowed the minecart to 25% speed, it touched the platform-block and I was pulled in, afterwards the minecart was accelerated again. Maybe I did not save the config but I was not able to reproduce it. Often I get an error, that flags must be enclosed (obviously a syntex error on my side) and the config resets itself, other times, I get no error and the blocks are simply ignored, both on test tracks and "real" applications with redstone all around (even though the brakes should ignore the redstone).

Code:

(Brake-Block)<ControlBlock>
            <BlockType>GRAVEL</BlockType>
            <SpeedMultipliers>
                <SpeedMultiplier>
                    <Redstone>disables</Redstone>
                    <Multiplier>0.25</Multiplier>
                    <Direction>Any</Direction>
                    <Passenger>default</Passenger>
                </SpeedMultiplier>
            </SpeedMultipliers>
            <Catch/>
            <LauncherSpeed/>
            <Eject/>
            <Platform/>
            <Station/>
            <SpawnMinecart/>
            <KillMinecart/>
            <Elevator/>
            <AutoConvertToPoweredRails>false</AutoConvertToPoweredRails>
        </ControlBlock>
(Platform / Playercatcher-Block)<ControlBlock>
            <BlockType>LIGHT_GREEN_WOOL</BlockType>
            <SpeedMultipliers/>
            <Catch/>
            <LauncherSpeed/>
            <Eject/>
            <Platform range="4" redstone="disables">true</Platform>
            <Station/>
            <SpawnMinecart/>
            <KillMinecart/>
            <Elevator/>
        </ControlBlock>

I would really appreciate some help on the topic, as Afforess default config on his wiki is outdated and the brake one was copied and did not produce any errors, but did not work anyway.
