Montlaker,
As Dan indicated, V3.236 had many problems. One of these problems was that it stubbornly refused to use the LM14a interface for address "A1". It would instead use the standard X10 protocol and issue the 100% on commands as you have described.
I have also had problems with AHP not recognizing changes to macro's. As an example, if I were to change a module from a WS467 to a LM14a within a room, AHP may not update the interface within the associated macros. You can get around this by editing the macro and re-saving to the interface. Always check the log file to make sure the macro is issuing the proper commands (as you have done in your post).
If you do "downgrade" to a previous version of AHP (I would highly recommend this), you may need to edit your macros and re-save them to force AHP to use the downgraded commands. If you simply downgrade AHP and save to the interface, I do not believe the macros will be rebuilt.
Have fun,
Boiler
