Cannot import anything

[mwandelt]

When trying to import data from a CSV file, the "Field Mapping" block in the second step is empty, and the JavaScript console says: "TypeError: value is undefined (espo.min.js:138:1)". I tried with Firefox 59.0.2 (Linux) on two different machines, both using EspoCRM 5.1.2. Is this a known bug, or is it specific to my installations? Any idea what's causing this issue? The data/log file on the server has no entries correlated with this error.

if it doesn't work, attach the file in PM, please.
If it works, the problem is with your installations
