There are of course 'problems' and 'problems'.
Many 'problems' nowadays do not mean that an aircraft is dangerous or unairworthy - just that there may be slight anomalies with log cards or documentation.
I can understand a civvy maintenance organisation being confronted by problems if they are perhaps encountering a 'BMAR' or similar for the first time,it would probably have been quicker and cheaper to order a new fleet of gliders than undertake this long winded fiasco !
