Mempool fields in Debug Windows show "N/A"

[Relaxo143]

Expected behavior
Show and update the number of txs in the mempool in real time

Actual behavior
Shows "N/A"

To reproduce
Tried restarting the node. reinstalling Core and running it without the .conf file. Issue persists. I'm not sure how to reproduce it.

System information

v0.19.0.1 downloaded from bitcoincore.org

Win10, Ryzen 5 2600, SSD

It happened after upgrading from 0.18.1 to 0.19.0.1
getrawmempool returns transactions, so the mempool is working. It appears to be a GUI issue

This will be fixed with #17427.

I see the same issue with the new release Bitcoin Core version v0.19.0.1 (release build). This is the command line that I used:

bitcoin-qt -txindex -datadir=/redacted -persistmempool=0 -server -rpcuser=redacted -rpcpassword=redacted

getmempoolinfo rpc does report seemingly correct data.

Hi reporting the same issue, both "Current number of transactions" and "Memory Usage" both = N/A, upgraded from v0.18.1 --> v0.19.0.1

Closing this, as the fix has been backported to the 0.19 branch in 2aba76c and a284bbb.
