Are you starting a brew or finishing one off?
Rule of thumb to keep handy when using any kind of enzyme in brewing; enzymes are proteins and proteins don’t mix well with bentonite or with sulfur dioxide. Always wait at least 12 hours, like your package directions dictate, between using sulfur dioxide and one of the other two products. In your particular situation, I would say that you could re-add some of the pectic enzyme, say, a half dose or so. All you’re doing is settling out pectins anyway and it should not harm the must.
Just so you’re aware, enzymatic activity can also be inhibited by high alcohol, low temperatures as well as high temperatures. Always try to avoid these situations but if you can’t, it’s generally alright to use a little more enzyme than you normally would to account for it
