Human readeble traffic TCP port 80,etc.

I start a new question then it didn't work with old questiones, I can't see answers of others users. So, in few words: I captured traffic of my smartphone p9 lite using commview and leaving my router without password. I've open on the smartphone different site, https and http.

I have exported log file data from commview in .cap file that wireshark can open, I've run then wireshark and see all the lines, filter the TCP connection but nothing to do I can not read data in human readeble format, I've choosed in name resolutions properties the flag of "resolve network IP addresses" but no way to read the data. Most of tcp are of port 443 that I know it's https but there was also some port 80 but nothing to do. The question is why I see just TCP 443 data and some TCP 80 and why in wireshark I just see info in ASCII and not in human readeble format? thank you again
