Your count for the floats is off by one-- there are six, not five. Either read the whole file and just discard any you don't want or use the '*' to ignore a field.
You'll also have better luck with
fmt=['%s%s' repmat('%f',1,6)];
to return the date fields as strings than character. BUT, the better yet would be to use the new(ish) '%D' date conversion field descriptor and return datetime values directly...
>> fmt=['%{yyyy-MM-dd}D' '%{HH:mm}D' repmat('%f',1,6)];
>> frewind(fid)
>> data=textscan(fid,fmt,'collectoutput',1,'headerlines',1)
data = 
    [4x1 datetime]    [4x1 datetime]    [4x6 double]
