PF_ADD_TOPIC breaks parameters within topic's values

I was experimenting with the SDK's parameters to improve my plugin user experience. Basically, I just want some settings to be collapsed in an "advanced settings" section.

To do so I used the PF_ADD_TOPIC and PF_END_TOPIC macros. The topic is well displayed in premiere in the effects pannel, but all the settings within the topic's section have a value of zero during the execution of the program, no matter the parameters within the section.

• I tested it with another plugin I am working on, and I have the exact same problem
• All of the other parameters outside the topic are working
• I tried to remove the AEFX_CLR_STRUCT but it changed nothing

static PF_Err 
ParamsSetup (	
	PF_InData		*in_data,
	PF_OutData		*out_data,
	PF_ParamDef		*params[],
	PF_LayerDef		*output )
{
	PF_Err err = PF_Err_NONE;
	PF_ParamDef	def;

	AEFX_CLR_STRUCT(def);
	PF_ADD_FLOAT_SLIDERX(
		STR(StrID_Ratio_Param_Name),
		TINTER_RATIO_MIN,
		TINTER_RATIO_MAX,
		TINTER_RATIO_MIN,
		TINTER_RATIO_MAX,
		TINTER_RATIO_DFLT,
		PF_Precision_TENTHS,
		PF_ValueDisplayFlag_PERCENT,
		PF_ParamFlag_RESERVED1,
		RATIO_DISK_ID
	);

	AEFX_CLR_STRUCT(def);
	PF_ADD_COLOR(
		STR(StrID_Color_Param_Name),
		TINTER_DEFAULT_RED,
		TINTER_DEFAULT_GREEN,
		TINTER_DEFAULT_BLUE,
		COLOR_DISK_ID
	);

	AEFX_CLR_STRUCT(def);
	PF_ADD_TOPIC(
		STR(StrID_Debug_Topic),
		DEBUG_TOPIC_DISK_ID
	);

	AEFX_CLR_STRUCT(def);
	PF_ADD_FLOAT_SLIDER(
		STR(StrID_Border_Width),
		BORDER_MIN_WIDTH,
		BORDER_MAX_WIDTH,
		BORDER_MIN_WIDTH,
		BORDER_MAX_WIDTH,
		AEFX_AUDIO_DEFAULT_CURVE_TOLERANCE,
		BORDER_DEFAULT_WIDTH,
		PF_Precision_INTEGER,
		PF_ValueDisplayFlag_PIXEL,
		PF_FSliderFlag_NONE,
		BORDER_WIDTH_DISK_ID
	);

	AEFX_CLR_STRUCT(def);
	PF_END_TOPIC(
		DEBUG_TOPIC_DISK_ID
	);

	AEFX_CLR_STRUCT(def);
	out_data->num_params = PLUGIN_NUM_PARAMS;

	return err;
}

Here is the related part of my header file :

#define TINTER_RATIO_MIN		0
#define TINTER_RATIO_MAX		100
#define TINTER_RATIO_DFLT		50

#define TINTER_DEFAULT_RED		255
#define TINTER_DEFAULT_GREEN	255
#define TINTER_DEFAULT_BLUE		255

#define BORDER_MIN_WIDTH		0
#define BORDER_MAX_WIDTH		0
#define BORDER_DEFAULT_WIDTH	5

enum {
	// Always keep first
	PLUGIN_INPUT = 0,

	// Effect settings

	TINTER_RATIO,
	TINTER_COLOR,

	// Debug settings

	BORDER_WIDTH,

	// Always keep last
	PLUGIN_NUM_PARAMS
};

enum {
	// Effect settings

	RATIO_DISK_ID = 1,
	COLOR_DISK_ID,

	// Debug settings

	BORDER_WIDTH_DISK_ID,

	// Topics

	DEBUG_TOPIC_DISK_ID,
};

Can someone tells me / spots / knows what am I doing wrong ? If you also have used this parameter in the passed, I am interested in working code snippets.
