PROBLEMS WITH THE COLOR DIFFERENCE IN THE MODULES LIBRARY AND DELOPMENT

HELLO, I HAVE A PROBLEM WITH THE COLORS OF THE PICTURES. I USE LIGHTROOM CLASSIC CC AND THE INTENSITY OF THE COLORS LOOKS DIFFERENT WHEN I AM IN THE DEVELOP MODE AND THEN RETURN TO THE LIBRARY MODE. IN THE LIBRARY MODE THE COLORS ARE LESS INTENS THEN IN THE DEVELOP MODE. I HAVE NO CLUE HOW THIS IS POSSIBLE. I AM USING A MAC COMPUTER AND THIS PROBLEM IS SINCE A INSTALLED THE NEW VERSION OF CATALINA. I USE A CALIBRATING TOOL FOR MY BENQ SCREEN WHICH IS CALLED PALLETMASTER AND THIS WAS A 32-BIT VERSION BUT CATALINA DOES NOT SUPPORT 32-BIT VERSIONS BUT REQUIRES 64-BIT VERSIONS. SO I DID INSTALL ALSO A NEW 64-BIT VERSION OF PALETMASTER AND I CALIBRATED MY SCREEN. THEN I NOTICED THAT THE COLORS DID NOT MATCH WHEN I AM LOOKING AT IT IN THE DEVELOP MODE IS IT MUCH INTENSER THEN IN THE LIBRARY MODE. HOW CAN I FIX THIS, THAT I SEE THE SAME COLOR RENDERING ? HOW DO I KNOW I DEVELOPED MY PHOTO IN THE RIGHT WAY I WANT IT TO LOOK ? BECAUSE WHEN I RETURN TO THE LIBRARY MODE TO EXPORT THE PICTURE THE COLORS ARE LESS INTENS THEN I SAW IT IN THE DEVELOP MODE. IT IS VERY STRANGE THAT ALL THIS HAPPENED AFTER THE NEW VERSION OF CATALINA AND THE NEW 64-BIT VERSION OF PALLETMASTER. I AM USING LIGHTROOM CLASSIC CC FOR A LONG TIME NOW AND I NEVER BEFORE HAD THIS PROBLEM. CAN ANYONE HELP ME WITH THIS PROBLEM ?
